Comment 4 by ClusterFuzz, Sep 4

Labels: Fuzz-Blocker ReleaseBlock-Beta M-71
This crash occurs very frequently on linux platform and is likely preventing the fuzzer binaryen_wasm_fuzzer from making much progress. Fixing this will allow more bugs to be found.

Marking this bug as a blocker for next Beta release.

If this is incorrect, please add ClusterFuzz-Wrong label and remove the ReleaseBlock-Beta label.
