This looks like it is related to accessibility IPC, which Trevor and Aaron have been looking at.

This crash is 100% reproduce for me. STR: double-click to select text in the following Google Doc. I can't reproduce in any other Google Docs. I am running Nightly 54 on Windows 10 with dom.ipc.processCount = 999.

I hit this crash multiple times per day when clicking in Google Docs. I had to switch to Aurora channel because Nightly is so crashy.

trev is this the same as bug 1326084? I see this and that bug so frequently that nightly is unusable.

Not entirely sure, but if the fix for 1326084 is correct then this is probably different.  That said I'm going to start looking at this today.
