(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 When I attach the to crashed process with gdb all I can get is this: $ gdb /usr/bin/ark 6582 GNU gdb 6.4-debian Copyright 2005 Free Software Foundation, Inc.
