With the right man pages installed you could do 'man execve'.
Maybe it doesn't tell you much, but I can see that it is not perl that 
is crashing, it is the loader that tries to fork the perl process,
before perl gets started then. In your other mail you have found the 
reason already. I have no idea how this could happen, but I wouldn't
trust your hard disk anymore.
