http/tests/misc/heic-accept-header.html


is a flaky crash on macOS wk2. 


HISTORY:
https://results.webkit.org/?suite=layout-tests&test=http%2Ftests%2Fmisc%2Fheic-accept-header.html&style=release

Looking at the history this appears to impact both intel and Apple Silicon Macs. However, the crashes do appear to be more frequent on Apple Silicon than they do on Intel. There was no crashlog/assertion/message gathered for this crash so I am going to attempt to reproduce it.

I have not yet been able to find any crash logs for this test, but I am currently investigating. Further, I have also not been able to reproduce a crash for this test. I have attempted in iterations up-to 10000, and I am currently running it in a test list in the same order from one of the bots where the crash has occurred, but so far no reproduction. 


This is also a newly introduced test at: https://commits.webkit.org/261131@main

Test gardening commit 262379@main (657b4590736f): <https://commits.webkit.org/262379@main>

Reviewed commits have been landed. Closing PR #12215 and removing active labels.

I was finally able to find a snippet of the crash log on one of the bots:
