Labels: Fuzz-Blocker ReleaseBlock-Beta M-70
This crash occurs very frequently on mac platform and is likely preventing the fuzzer puzzor_svg 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.
