I am not able to reproduce this issue with iterations, test-list, debug or Guard Malloc.

Landed proper expectations in https://trac.webkit.org/changeset/255979/webkit

There were no failures on wk1 between r254153 and r255154, so I don't see evidence for this claim. Also, it fails on wk2 too, including in this range.

I can reproduce this by running the test in iterations x5000 ( failed 18 times )

Set proper expectations here: https://trac.webkit.org/changeset/256506/webkit
