Wasmtime GitHub notifications bot (Aug 28 2025 at 23:06): Wasmtime GitHub notifications bot (Aug 28 2025 at 23:06):cfallin opened PR #11564 from cfallin:null-exnref-global-initializer to bytecodealliance:main:
Previously, the
Global::get()implementation lumped exnref types in with other anyrefs and wrapped the raw GC ref in an anyref type. This isn't appropriate for exnrefs as they are not anyrefs.Found via OSS-Fuzz.
Fixes #11561.
