stack overflow

Stack overflow could cause the program to terminate by sending SIGABRT signal.  You can detect this with latest gcc compiler(4.2 above) under gdb debugger.

Run the program under gdb and once the program terminates, check call stack(run bt command in gdb) and see your call stack for a call to the function __stack_chk_fail().

The interface __stack_chk_fail() will abort the function that called it with a message that a stack overflow has been detected. The program that called the function shall then exit.

Below is the output you will get when run xxxxxx program under gdb.

 /Developer/usr/bin/gdb  xxxxxx

(gdb) run

Program received signal SIGABRT, Aborted.
0x92fb9a6a in __pthread_kill ()

(gdb) bt
