The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on".
Evaluation of the expression containing the function
(safe_debug_print) will be abandoned.
When the function is done executing, GDB will silently stop.
