This crash seems to be elusive. Since the crash appears to be in a GC marker thread, I tried various values of JSC_slowPathAllocsBetweenGCs, but have not prevailed in reproducing this issue yet.

Looking at this now: https://build.webkit.org/builders/Apple%20El%20Capitan%20Release%20WK2%20%28Perf%29?numbuilds=200 It seems like the bug is not happening anymore.

Tried rebooting the bot, given that this started soon after a reboot. Still no crashes at all.
