> These crashes are also occurring on the 64-bit GTK build, but only the release configuration. Specifically, fast/js/random-array-gc-stress.html was spotted crashing occasionally[1].

> Furthermore, I can reproduce these crashes consistently when running the test262 suite[2]. I'm now doing a bisect with each step being marked good or bad depending on the crashes occurring when running test262. At the moment the offending commit list is narrowed down between r121837 and r121895.

The bisecting amounted to nothing valuable, the crashes started occurring after the parallel GC was enabled for the GTK port in http://trac.webkit.org/changeset/121869.
