Hi @dwblaikie, @yonghong-song,

Could you please take a look at this pull request?
Rationale is here: https://github.com/llvm/llvm-project/pull/91422#issuecomment-2101104708
The CI failure seems to be a fluke as it is reported for `DataFlowSanitizer-x86_64 :: release_shadow_space.c` which is completely unrelated (also CI for 91424 passed).

@dafaust, @jemarch, @4ast, fyi.
