BUG: jobs -d causes core dump

[Felix Rosencrantz <f_rosencrantz@yahoo.com>]

When I attempt to run "jobs -l -d" I get a core dump, with the following
stack trace.

I think the problem occurs when there is a job in the background that was
started in the current directory.  It seems like the pathname in the Job
structure is a NULL pointer at that time.
