scoob, I didn't dig hard, but signature might start at Firefox 22.

I looked at https://crash-stats.mozilla.com/report/list?product=Firefox&query_search=signature&query_type=contains&reason_type=contains&date=2013-09-22&range_value=14&range_unit=days&hang_type=any&process_type=any&signature=mozalloc_abort%28char+const*+const%29+|+NS_DebugBreak+|+nsACString_internal%3A%3AAssign%28char+const*%2C+unsigned+int%29 and none of the 4 unique stacks I examined** have the same stack. Not too surprising with OOM.

topcrash for TB24.0.1 ~#20. However, this might be multiple bugs, there are multiple stacks (waiting on help from bug 557234)

oldest firefox crash found is 22.0a2
