Topic: wasmtime / PR #8410 Fix use-after-free in externref example

Wasmtime GitHub notifications bot (Apr 19 2024 at 04:04):

alexcrichton opened PR #8410 from alexcrichton:fix-externref-use-after-free to bytecodealliance:main:

This fixes a typo in the externref.c example where a deallocated wasmtime_val_t was used by accident. Additionally this introduces scoping to prevent this from arising again.

This is now declared inside this block, but then reused in the other block and has wasmtime_val_delete called outside of the block. Can we move it up, out of this block then?
