I beg you to try my suggestion first.  All it involves is: download
the software; unpack; build.  Total elapsed time is probably under ten
minutes, most of which is unattended, and it's virtually guaranteed to
produce a usable core file.  On the other hand, the possibility of
creating a smaller example is not certain, will probably take at least
an hour of trial and error, and may have the result that I require you
to look at the full Latte distribution after all.  Though I'll
certainly make that effort if necessary, I think trying plan A first
is more direct for both of us.

No.  There's a lot of exception handling in Latte, and most of it
works perfectly well.

Yes, it works fine.

I'd like to give this a try even though your example worked.  What's
the Right Way to get libgcc compiled with specific compiler flags?

Thanks,
