Hmm, not really.  There are other similar crash reports but not too many...  Do you have a custom dictionary installed by any chance?

All crashes are Mac. https://crash-stats.mozilla.com/report/list?signature=mozInlineSpellWordUtil%3A%3ASplitDOMWord#tab-reports

What's up with that?

It looks like we're running this code off as a runnable dispatched to the thread. Perhaps the way that works on OS X is different enough that it changes timing or whatever to such a degree that e.g. nodes are dead (or their contents have changed) when we try to run spellcheck on them?

I couldn't reproduce at the time, so no, I guess...
