Status: RESOLVED WORKSFORME

(Core :: DOM: Content Processes, defect)

Description

[Johannes Pfrang [:johnp]]

Just crashed with this signature (no STR), but looking at the crash stats this started with the September 5th build in which jemalloc4 had been enabled and has je_isqalloc in the stack. atm windows+amd64 only fwiw.

[(Away)]

This signature is doubly-spurious: the je_isqalloc frame was not really on the stack (it was a bad stack walk), and this was a two-process dump where the server looked at the less-interesting stack.

The "ipc channel error" field may help point this bug in the right direction: it is somewhat of a grab bag but many of them say HangMonitor.
