Can you try the following commands from gdb and report back? 1) info thread just for the sake of info 2) thread 2 Expect something like "switching to thread 2 blah blah blah" frame 2 Expect something like "#2 hex-adress in pthread_mutex_lock()" info reg This will print the registers' contents. After this I will have more questions, but first I need the answers above. Again, please do not exit from gdb unless it is critical for you (for example you have to switch off your computer). If you have to exit and restart kdesktop, the next time you need to repeat the commands already typed + the new ones.
