Thanks, but I'd prefer if you checked your patch in.  The bug reported
on 23555 is actually composed of two issues: (a) what to do when GDB
can't determine the CWD, and (b) the segmentation fault that happens
when we try to call warning too early in the code.  Your patch fixes
(b), and I still didn't sit down to figure out how to approach (a).  So
it's best if we just go ahead and avoid the segfault for now.

Thanks,
