Wasmtime GitHub notifications bot (Apr 27 2026 at 15:02): Wasmtime GitHub notifications bot (Apr 27 2026 at 15:02):alexcrichton opened PR #13206 from alexcrichton:adjust-differential to bytecodealliance:main:
Fuzzing over the weekend found a failure where a wasmtime "rhs" failed with a trap and a wasmtime "lhs" failed with "gc heap not big enough". This is expected to be effectively equivalent but the method of testing whether a Wasmtime error is "non deterministic", which running out of GC heap space basically is, differed slightly with some other code which led to this differential failure.
