A stack overflow could do that ... also lack of symbols could be
causing problems with stack unwinding... in other words, what
you see may not be really what you are getting.
Maybe Peter could reproduce this with the shipping binary? If
I recall correctly, you save symbols for those, right? Given that,
you could then debug a dump file.
Another possibility would be to compress and upload the symbols
for the nightlies (or even include the symbols in the .msi ?)
If the stack walk has any relationship to reality, which I tend
to doubt in the absence of symbols, these to frames seem
interesting:

It looks like something allocated about a megabyte of stack between
the two frames. Do we use alloca?
Thanks,
