Do you know of any JS changes from March 3–4 that might have provoked this crash?

Isn't this a dupe of bug 980537 per comment 170? We haven't hit it since the day that bug was backported (see bug 980537 comment 36).
Flags: needinfo?(bobbyholley)
Similar to what kairo mentioned in bug 983976, it is a lower occurrance so I'll close it for now unless it appears more often or we can find reproducible steps.

bholley: this intermittent crash seems to have spiked today. The stack trace is the same, but the crash addresses have changed. Does the fact that the crash address is sometimes jemalloc uninitialized memory, sometimes JS_FREE_PATTERN, or sometimes a null pointer suggest anything? It seems a little strange that pointers so many types of memory allocations would be passing through the same code path.

The recent crash addresses are 0xa5a5a5d1, which is 0xa5a5a5a5 + 44. firebot says 0xa5a5a5a5 is jemalloc allocated uninitialized junk memory. But crash reports from earlier today also included 0x2c (44) from a NULL pointer access.

In comment 106 from March, jandem noted that the crash address then was 0xdadadae6, which was 0xdadadada + 12 == offsetof(BaseShape, compartment_). 0xdadadada is JS_FREE_PATTERN (deallocated JSArena - GC()d).
