again, so I can't confirm this. I took a core with 'dumper' but gdb

I think you need gdb 11 (for this patch set [1], which is also in cygwin's
gdb 10 package) to read x86_64 cygwin core dumps.

Thanks, this was the problem. But the core dump wasn't much help anyway,
the stuff I was interested in was pre-exception, and the backtrace
seemed to stop at the exception handling (unlike when 'live' debugging
when the stack trace continued).
Hmm.. That's probably a bug of some sort, since I think the two methods
should produce the same results...
