How did the app run before?


check the "threads" window.

you may be in the wrong thread (OS may add threads, even if your app 
does not have them)


did you do stepping, or did you run F9?

what OS?

what version of gdb?


http://wiki.lazarus.freepascal.org/GDB_Debugger_Tips#Log_info_for_debug_session

provide a log (if not possible then at least  the output of the "debug 
output" window/ open this before the problem happens)


there should be a lines like

*stopped, reason=...

the last such line should give a clue.
