Sorry, that's not a test case. A binary, command line, necessary input
files, transcript, and preferably backtrace of the crashing GDB binary
- that's a testcase. I'm not going to jump through hoops trying to
find an x86-64 system and build CVS gnat1 on it.
That was exactly why I said it wasn't that useful! And I have no idea how
to start in trying to find a smaller case.
Stabs is a bad choice on a 64-bit platform, as I'm sure you know.
Does x86-64 GNU/Linux even keep code in the 32-bit region that stabs
can describe?
Indeed I didn't think it would work at all. But in fact it worked just
fine and I was able to find the problem.
