Here's the output from the program on my machine:
Father Sweet child in time: 8826 you'll see the light
It seems the exec is happening. I'm using kernel 2.4.21-0.18mdk with glibc-2.3.1-10mdk on a Mandrake 9.1 system running on a P3 Machine.
This is very troubling. The exact same program gets stuck on my machine right after "Sweet child in time", and I get no further printings. This means that neither the execlp() nor the perror() after it were called. The process table looks pretty weird, too:
alexsh 12056 0.2 0.1 3624 396 pts/0 S 10:15 0:00 ./thfork alexsh 12057 0.0 0.0 0 0 pts/0 Z 10:15 0:00 [thfork] <defunct> alexsh 12059 0.0 0.1 3624 424 pts/0 S 10:15 0:00 ./thfork
Can you please post the link command used to generate the binary? did you remember to lni libpthread? because if you didn't you're using the standart fork/exec instead of the thread aware ones from libpthread and this explains what you're seeing.
