Two gdb 6.4 usage queries

[Jon Grant <jg@jguk.org>]

Hello,

I have to queries, I hope someone will be able explain or point me to
documentation.
(I am running Kubuntu 6.06 on a 32bit Althon.)

1) Shared library methods are relocated when they are used by a program,
is there a way to view the present running address of these shared
library functions/methods from gdb?

2) I would like to get to see the same backtrace that the kde crash
handler has generated

callstack like:
[KCrash handler]
#6  0x00000000 in ?? ()
#7  0xb7182f3e in QApplication::internalNotify () from
/usr/lib/libqt-mt.so.3
#8  0xb718313a in QApplication::notify () from /usr/lib/libqt-mt.so.3
#9  0xb78617ab in KApplication::notify () from /usr/lib/libkdecore.so.4
#10 0xb71141c5 in QApplication::sendSpontaneousEvent ()
   from /usr/lib/libqt-mt.so.3
<snip>

When I attach the to crashed process with gdb all I can get is this:

$ gdb /usr/bin/ark 6582
