Labels: Fuzz-Blocker ReleaseBlock-Beta M-69
This crash occurs very frequently on linux platform and is likely preventing the fuzzer inferno_layout_test_unmodified 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.
Similar to or duplicate of  Issue 861882 .
