This looks like a normal OOM crash, trying to allocate memory for code as part of regexp processing. I'm not sure how much memory was requested and why allocation failed.

Automatically applying components based on information from OWNERS files. If this seems incorrect, please apply the Test-Predator-Wrong-Components label.

I think applying Blink>JavaScript>Runtime is wrong. Blink>JavaScript would be more appropriate. I will kick-off a separate email thread to fix that problem.

ClusterFuzz testcase 6562255910207488 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
