Package: fbb
Version: 7.011-1
Severity: normal
X-Debbugs-Cc: mike@elite.uk.com
Dear Maintainer,
I've run into a crash bug when using the FBBDOS feature of fbb.
Using the 'DIR' command to list files works in FBBDOS's root directory.
If any non-empty subdirectory is entered with the 'CD' command, as subsequent
'DIR' will crash fbb.
Additionally, where 'DIR' does work, the file sizes and date stamps are wrong.

I was able to produce an xfbbd binary that could perform the above operaiton without crashing by using
DEB_CFLAGS_SET=-D_GNU_SOURCE , but I don't know if that will have wider consequences. The file sizes
and dates returned by 'DIR' are still wrong but, oddly, different.
