It seems like it's been in this state for a while. Most recent crash stack trace (I must admit, I have no idea what this means):

This only happens on Chromium Win. Mac and Linux never saw this particular crash since test was enabled. They show 1 and 2 crashes on flakiness dashboard, but that was another one, caused by a patch since reverted.

[Dmitry Titov]

I couldn't get it to repro on any platform, we looked at JS dump with Mads Ager and the best theory is that it's out-of-memory situation since it fails in trying to allocate a function object (locals before allocation are initialized, after - uninitialized). 

Also, I don't see this crash on the flakiness dashboard, all the latest runs are green. Will watch it for a while and enable if it doesn't fail any more.

[Vsevolod Vlasov]

This is still crashing sometimes on mac and linux debug builds and misses expectations on win debug every once in a while.
