Again, "Crash Reason: EXCEPTION_BREAKPOINT", like bug 1127260 and bug 1127292.

It's interesting that all three have nsTextFrame::ReflowText on the stack.

Crash Reason 	EXCEPTION_BREAKPOINT
Crash Address 	0x6e4191fa

First 10 frames from the stack:

There is also a crash on OS X in the list. So expanding platforms to all.
