Bug#1072299: Compositor-related crashes

All right, I've figured out what was going on, as well as a fix. Going back to that backtrace I posted some months ago, which I've seen crop up again and again: #0 0x00... in partition_alloc::internal::OnNoMemoryInternal(unsigned long) () #1 0x00... in partition_alloc::TerminateBecause

Bug#1072299: Compositor-related crashes

I'm going to need a spot of help with this. I have Chromium running under GDB, with surprisingly low overhead (I can browse like normal if I drop the --single-process flag). As far as I could find, the "trap invalid opcode" error reported in syslog is synonymous with a SIGILL, so I set "handle SIG

Bug#1072299: Compositor-related crashes

Sigh, spoke too soon. Chromium still crashes in both modes (tab and browser) even without Firefox running, but much less frequently. I had a good half-hour without crashes after closing Firefox, enough to lead me to think that was the cause. At this point, we're probably better off waiting to see
