Accepting bug. Setting target milestone to M8. Charlie, I can't reproduce this with my build from today at all. Things work just fine. I'll try a fresh pull tomorrow and see if I can reproduce the crash.

FYI We narrowed this down to something in Charlie's build environment. One of the libraries, xpcom I believe, that the spellchecker library is linking against is bad.

Moving to M9.

Moving all spellchecker/text services related bugs to M11 since I will still be working on AutoComplete features through M10.

Charlie, can we close this bug? I think we figured out that your _MSC_VER environment variable was set incorrectly.

Yep.

verified in 9/9 build.
