The STL implementation used by kf::vector::resize(count, value) on older 32-bit Windows targets expects a memcmp symbol that the legacy CRT does not export. This manifests when resizing integer vectors and causes the binary to pull in unsupported legacy memcmp references on Windows XP–7.

• Overview

  • kf::vector wraps STL vector behavior and relies on the standard scalar-fill implementation behind resize(..., value).
  • On legacy 32-bit Windows, that implementation hits a compatibility issue with the old CRT, which is why the build needs the WDK-provided symbol.

• Changes

  • Added the WDK compatibility library to the affected test target in test/CMakeLists.txt.
  • Scoped the linkage to 32-bit targets only via CMAKE_SIZEOF_VOID_P EQUAL 4, so modern 64-bit builds remain unchanged.
  • Included a brief compatibility note documenting the Windows XP/7 requirement and why the linkage is necessary.

kf::vector<int, PagedPool> test;
test.resize(10, 1);

• Why this matters
  • This preserves the standard STL scalar-fill path for legacy 32-bit Windows without altering functional behavior on supported platforms.

• Fixes kf::vector resize method leads to the use of unsupported on old 32-bit systems (Windows XP-Windows 7) memcmp function #50

The failure is the legacy 32-bit Windows STL compatibility issue: older Win XP/7 CRTs do not export the memcmp symbol used by scalar-fill paths in STL. The fix is to link WDK::MEMCMP for 32-bit targets, which matches the upstream WDK module behavior (FindWdk.cmake does this automatically).
