The latest published version (0.6.12) does not include these commits, which includes #162 which removes mem::uninitialized uses and lets the crate run under miri.
I was trying to run what appears to be a UB-based issue in a rust-analyzer (rowan) patch under miri and ran into this.
You should probably also consider submitting a RustSec advisory for the miri-disapproved mem::uninitialized usage.
