Details
Some of our shmem uses immediately fill up the buffer that they allocated which - in case of low memory situations - will trigger a SIGBUS signal. If we flag these allocation sites with AnnotateOOMAllocationSize()
we should be able to categorize those crashes as OOM and also detect how much memory we're allocating.
For example we could call AnnotateOOMAllocationSize()
here to record bufSize
and then clear it to 0 here and here.
This would correctly detect most crashes in bug 1631680 as OOMs.
