alexcrichton opened PR #9393 from alexcrichton:fix-under-aligned-empty-mmap-pointer
to bytecodealliance:main
:
This commit updates platform implementations of
Mmap::new_empty()
to use a shared helper to create a pointer with a higher alignment than one. This fixes a debug assert tripping in niche configurations of the pooling allocator where if no virtual memory is given and table lazy init is disabled then a module could trip a debug-only assert about a slice being created from a raw pointer that is not properly aligned. The fix here is to use a helper that starts with an over-aligned empty slice which is then casted down to a byte slice.<!--
