I am not able to reproduce this with the same testcase but am getting this exact same crash constantly after some time. The callstack above includes the output of NSPR_LOG_MODULES. Tested with m-c changeset: 113925:20ec9014f220

A space is required between @ and the signature for the connection to crash stats.
Crash Signature: [@ fim_process_event]

Sorry, haven't mentioned that. I am not able to reproduce the testcase with the same seed value during fuzzing.

Ethan: some sort of race condition or logic flaw - can you look into it? Cristoph: any reasonably likely way to provoke this?

As it's a NULL-ptr deref, an assertion might help. Or run a debug build under gdb and catch the failure

(In reply to Randell Jesup [:jesup] from comment #6) > Ethan: some sort of race condition or logic flaw - can you look into it? > > Cristoph: any reasonably likely way to provoke this? It's one of the crashes which come up during SDP fuzzing but are not reproducible with the same testcase later on.
