It's #28 top browser crasher in 12.0b1.
Assigning to Brian to start since there's nothing in the pushlog that jumps out at me. Brian - please let us know if there's any information the crash-kill team can pull for you or anything QA can help test.
Possibilities: 1. Maybe the entry is corrupted on disk and we read an invalid "len" which is very large; then we try to allocate a very large amount of memory and crash. This shouldn't cause a top-crasher though! 2. Maybe there is an uninitialized memory read 3. Maybe there is a race condition where another thread is corrupting the memory.
Hey Brian, anything we can do here? It's significant enough volume on beta at this point.
Apparently there's some problem with Socorro and URLs that contain * characters that are not escaped (which they actually should be): The working URL for the reports is https://crash-stats.mozilla.com/report/list?signature=mozalloc_abort%28char%20const%2A%20const%29%20%7C%20mozalloc_handle_oom%28unsigned%20int%29%20%7C%20moz_xmalloc%20%7C%20nsNSSCertificate%3A%3ARead%28nsIObjectInputStream%2A%29
The reports I checked all said: OOMAllocationSize=4294901763 Which is 0xFFFF0003. So we're definitely getting garbage from somewhere. This appears to be a straight dup of bug 716594 which was fixed in 13, and the infallible NS_Alloc was backed out of 11, but nothing was done with FF12 apparently.

Let's move forward with backing bug 680556 from Beta again. This will finally be fixed in FF13 when bug 716594 lands.
(In reply to Kyle Huey [:khuey] (email@example.com) from comment #9) > https://hg.mozilla.org/releases/mozilla-beta/rev/6323a689d6f1 Thanks Kyle. This'll land in Beta 5 - we'll make sure to check to make sure that the crash #s drop off as part of crash-kill.
