Crash Data

This looks like a regression from the switch to the backtracking allocator.

Happened several times for me when visiting the linked URL, but now, in the same build, I can't reproduce it anymore.

Here's one of the crashes I saw: https://crash-stats.mozilla.com/report/index/72226f1f-d501-44bb-8bf4-f010f2150225
Oh, hmm, I just realized I was fooled by AWFY; the backtracking allocator hasn't even reached Nightly yet. So we'll see what happens with this once it did.
