Topic: wasmtime / PR #12755 Fix a `stacks` fuzzer regression

Wasmtime GitHub notifications bot (Mar 10 2026 at 20:35):

alexcrichton opened PR #12755 from alexcrichton:fix-fuzz to bytecodealliance:main:

This commit fixes an accidental mistake from #12542 where when the limit of stack frames for the fuzzer to capture is None then it meant that backtraces were never captured. This updates the assertion logic to handle a missing WasmBacktrace and the case that stacks.limit is None.
