--- Comment #1 from Matthias Zimmerman <matthias291999 at gmail dot com> ---
This is not a bug, you have a breakpoint in an area that you later call from
gdb, ie

>break exit
>p exit()
<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

Sometimes you can type `ret` until you get back to the right code, but not
always.

The stack and registers(if mangled) will not be restored(your program may go
into unintended areas) ie a while loop, in a state where it is a infinite loop.
