In the standalone packaging flow, CMT_INSTALL_INCLUDEDIR is not defined by CProfiles, so this generates an absolute /cprofiles install destination instead of ${CPROF_INSTALL_INCLUDEDIR}/cprofiles. This replacement also removes installation of the configured cprof_info.h and cprof_version.h, even though installed cprofiles.h includes both, leaving the headers component unusable for consumers. Restore the CProfiles destination variable and the generated-header install entries.

- Line 1200: Update the source static-label validation in append_context to
reject any label key already present in src via context_has_label_key(src,
label->key), including keys also present in dst, before copying or committing
labels. Add a regression test covering a source static label colliding with a
source metric-map label, while preserving label ordering and metric identity.
In `@lib/cprofiles/.github/workflows/build.yaml`:
- Around line 227-228: Update the workflow build commands to use the
matrix.preset configuration so each analysis job enables its intended sanitizer
or Valgrind settings, then run the configured test suite with ctest after
building. Preserve the existing CPROF_TESTS and CPROF_DEV options while ensuring

reviewed full immutable commit SHA, replacing mutable tags while preserving each
workflow’s existing behavior: lib/cprofiles/.github/workflows/packages.yaml

and softprops/action-gh-release references at those sites, including both
actions in build.yaml lines 134-139.

CPROF_VERSION_STR variable instead of the undefined CPROFILES_VERSION_STR,
ensuring CPack receives the project version for package metadata and filenames.

In `@lib/cprofiles/src/cprof_encode_opentelemetry.c`:
- Around line 1687-1701: Update the attribute encoding loop around
dict_add_attribute to resolve each attribute’s unit by matching
attribute_unit->attribute_key with the current attribute key, rather than
consuming profile->attribute_units by list position. Preserve the existing

Restore the selected analysis preset and run its tests.
The matrix still defines six analysis presets, but this command ignores matrix.preset. Every matrix entry now performs the same ordinary build. It does not enable the listed sanitizers or Valgrind, and it does not run ctest.
Configure with the selected preset, or pass equivalent analyzer flags for each matrix entry. Run the resulting tests.

Use the defined CProfiles version variable.
CPROFILES_VERSION_STR is not defined by this CMake project. Unless an external caller supplies it, CPACK_PACKAGE_VERSION remains unset or empty. CPack then omits the version from package metadata and filenames such as the Debian, RPM, and platform package names.
Proposed fix
-set(CPACK_PACKAGE_VERSION ${CPROFILES_VERSION_STR})
+set(CPACK_PACKAGE_VERSION ${CPROF_VERSION_STR})📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Provide a fallback for __CTR_FILENAME__ in every logging macro.
The five ctr_log_* macros use __CTR_FILENAME__ without a fallback. A consumer that includes this installed header without the library's build definition can fail to compile when it expands a logging macro. Define an internal filename macro that uses __CTR_FILENAME__ when available and __FILE__ otherwise, then use it in all logging macros.

official RISC-V psABI stack pointer alignment procedure entry stack frame minimum size
💡 Result:
<search_synthesis>
According to the official RISC-V psABI (Procedure Call Standard), the stack pointer (sp) must be aligned to a 128-bit (16-byte) boundary upon procedure entry [1][2][3]. In the standard ABI, this alignment must be maintained throughout the execution of the procedure [1][4]. Regarding the minimum stack frame size, the RISC-V psABI does not define a specific "minimum size" in bytes for a stack frame. Instead, the stack frame size is determined by the requirements of the individual procedure, such as the need to save callee-saved registers, allocate space for local variables, or provide space for outgoing arguments [2][3][5]. However, if a procedure chooses to use a frame pointer (fp) to maintain a linked list of stack frames, it must construct a "frame record" [6][5]. This frame record consists of two pointers (XLEN-sized values) on the stack: the return address and the link to the previous frame record [6][5]. When using a frame pointer, the frame pointer register points to the innermost frame, and the previous frame pointer and return address are stored at fixed offsets relative to the frame pointer (specifically, at fp - 2 * (XLEN/8) and fp - (XLEN/8) respectively) [6][5]. Note that for the ILP32E calling convention (designed for the RV32E ISA), the stack pointer alignment requirement is relaxed to a 32-bit (4-byte) boundary [1][2][3].

Reserve bootstrap space before aligning the stack. co_create sets the restored RISC-V sp to the allocation end. With a zero or small size, the downward-growing stack can place co_entry_trampoline's frame over co_context and corrupt entrypoint. Add a reserve sized for the supported toolchain and include it in the overflow checks. The 512-byte value matches the existing amd64 and AArch64 backends, but it is a libco convention, not a RISC-V ABI minimum.

Do not dereference a disabled timer's released event.
mk_event_timeout_disable() calls mk_event_del(), which clears the event registration but does not remove the Emscripten timer from ctx->timers. A later mk_event_wait_2() can therefore evaluate MK_EVENT_IS_REGISTERED(timer->event) after the caller frees timer->event.
Track registration state in timer-owned memory, or remove disabled timers from active scheduling and restore them when rearmed. Add a regression case that waits after freeing the disabled event.

Use detached mode for fire-and-forget timeout workers.
The fallback timeout implementations in mk_event_epoll.c and mk_event_poll.c discard their pthread_t. Their destroy paths close the read end, so the workers exit on the next write failure, but no caller joins or detaches them. Repeated timer creation can retain terminated thread resources and eventually make pthread_create() fail.
Add detached mode for these callers, or call pthread_detach(tid) after successful creation. Keep joinable mode for callers that call pthread_join(). The server clock worker is joined by mk_clock_exit() and does not need detached mode.
