Wasmtime GitHub notifications bot (Mar 31 2026 at 17:08): Wasmtime GitHub notifications bot (Mar 31 2026 at 17:08):alexcrichton opened PR #12910 from alexcrichton:fix-mpk-purge-index to bytecodealliance:main:
This commit fixes an issue with the pooling allocator when MPK is enabled, which is off-by-default at compile time. When a module is dropped all remaining images are purged from the pooling allocator, but the purging logic mistakenly used the wrong kind of index during purging which led to corruption of the pooling allocator itself. This fixes the logic and adds regression tests showcasing the issue as well.
