Changed paths: A JSTests/wasm/gc/bug247874.js M Source/JavaScriptCore/wasm/WasmTypeDefinition.cpp M Source/JavaScriptCore/wasm/WasmTypeDefinition.h Log Message: ----------- [Wasm-GC] Fix refcounts for compound type definitions https://bugs.webkit.org/show_bug.cgi?id=247874 Reviewed by Yusuke Suzuki. Compound type definitions that use type indices to refer to other types need to ref/deref the referred type definitions in order to keep them live (since the module's type signature list will not necessarily hold these types). Type definitions that only hold value types such as functions or arrays are fine as-is. * JSTests/wasm/gc/bug247874.js: Added.
