Hello again,
Hmm, I feel a bit stupid here -- it is just lucky the C program did not crash.
What I needed was
execl ("prog2", "prog2", (char *) 0);
That is, the program needed an argv[0] as the name of the program. Aparantly
Fortran is very dependant on this, and that is why it seg-faulted.
Thanks to Daniel R. Kegel who gave the suggestion!
Erik
