fitzgen opened PR #13512 from fitzgen:issue-135080-differential-fuzz-failure-after-alias-regions to bytecodealliance:main:

Stores without an alias region act like a fence: they clobber all regions. But we additionally need to update self.last_fence so that subsequent loads with regions don't get stale values forwarded past the regionless store.

Fixes https://github.com/bytecodealliance/wasmtime/issues/13508
