c - Program stops running on terminal but process persists -

when programme reaches end, prints out "sleep x seconds" executes sleep(x). however, after print happens, programme not hang @ , exits. using ps can see process still running in background (though may kid zombie).

very basic hierarchy of code:

main -> func1 -> fork multiple func2, set alarm() -(alarm goes off)> func3

using printf , fflush, func2 never gets entered it's called in func1 after successful kid process spawned.

i've tried using gdb appears mess when start using shared memory between parent/child fork().

there's on 1000 lines of code, posting rather much.

question: thought on how debug or have thought of may cause this? note: calls exit() coupled perror() before.

the issue wrong access shared memory. abruptly stopped programme without errors.

c gdb fork
