Status: RESOLVED DUPLICATE of bug 1014402

(Core :: JavaScript Engine: JIT, defect)

Description

[Kartikaya Gupta (email:[e-mail])]

This bug was filed from the Socorro interface and is 
report bp-b83e6bcd-13eb-4b0d-a843-39df72140522.
=============================================================

The last few ARMv6 nightlies have all been super crashy on my Galaxy Q phone. I filed bug 1011879 when I first ran into this, and that was fixed but there's other crashes. Any time I visit a page that is nontrivial (e.g. slashdot) it crashes. It also crashes if I just leave fennec running long enough, it seems like, because I often go back to my phone after doing something else and see the crash reporter up.

Crash reports since the 20th:

Please let me know if you'd rather I file separate bugs for every single signature, or if this bug can track them all.

Is this a dupe of bug 1013996?

It might be. It has been less crashy the last few days.
