When someone asks you to supply a backtrace (from a [[segmentation_fault]], for
example), here is roughly what you have to do.
Run the faulting program like this:
$ gdb --args PROGRAM [ARGUMENTS]
[...]
(gdb) run
[...]
[Segmentation fault.]
(gdb) bt
[...]
(!) This will only provide useful information if the executable (and additional
libraries) contain debugging symbols, or those are available separartely.
If you're one a [[Debian_GNU/Hurd_system|hurd/running/debian]], you'll have
to have the *hurd-dbg* package installed for debugging Hurd stuff, and perhaps
*libc0.3-dbg* as well if it's inside the glibc.
