From looked into the problem, it seems that I am not well to deal with the chunk range for dealloc Shmem when AllocChunk() fails. I will try to attach a patch to fix it.

Hi nical,
It seems that I am not well to define the number of chunks to dealloc shmem once it had a fail return from AllocChunk() in a Write() call. I think it is the reason to cause this crash. Could you please have review for the patch? Thanks

Not sure if it's the same root cause, but I got that crash yesterday, on current nightly: https://crash-stats.mozilla.com/report/index/3473914e-9b08-4dcd-a1ed-065ae0180220
