To refresh my memory on gdb I discovered that the info built from
txi47s.zip under djgpp 2.04 crashed while trying to access a gzipped
info file.


> set DEBUG=1
> gdb ./info/ginfo.exe
(gdb) run
..
Select M info

gunzip.exe < /dev/env/DJDIR/info.info.gz...
Program received signal SIGSEGV, Segmentation fault.
free (ptr=0x3c206578) at malloc.c:377
377	block->size &= ~1;
(gdb) n

was followed by a crash whose record was, in those details
which matter, the same as the bfdsymified trace from the
crash generated by calling "info gdb" from the command line.

Exiting due to signal SIGSEGV

I feel stupid about this but how do I get the gdb traceback
output to a file so I can quote it without retyping?  I
failed to find the answer in the gdb.info file.

Regards,
Frank
