Close.  Can you repeat the process, only before you give GDB the "run"
command, give it this one:
`(gdb) handle SIGFPE nostop`
and then complete the process as normal.  The mesa code is supposed to
cause SIGFPE, and then catch it.  Since GDB caught the signal, the catch
wasn't tested (and I think that is where the problem is).  The extra
command above tells GDB not to catch that signal.  It will print out a
message telling you that it was sent, though.
