Hello

Is there a way to get the "bt" command to output the library or ELF
binary file that the symbol orginates in? Would be handy if this could
even be the default:

Short example follows where I kill a process to show the backtrace
feature in use on my Ubuntu machine.

GNU gdb (Ubuntu/Linaro 7.2-1ubuntu11) 7.2

$ ulimit -c unlimited

$ /usr/bin/totem &
[1] 3581

$ kill -11 3581
[1]+ Segmentation fault (core dumped) totem
$ gdb /usr/bin/totem core

<snip>
Core was generated by `totem'.
Program terminated with signal 11, Segmentation fault.

#6 0xb77ada5f in main ()

#0 Doesn't show lib. I think this is glibc.

#6 Doesn't show the totem binary "/usr/bin/totem"

Please include my email address in any replies.
