Comment:
The backtrace I get from the packaged binary is useless, and I've
removed my source tree of it now after fixing the problem.

But the error is plain to see - look at the source fragments I pointed
out.  It's writing to element "minus one" of an array.  The overwrites
space it shouldn't.

I found that rebuilding without the -O3 flag made the bug go away -
possibly due to the static memory being spaced out differently, I don't
know.
