Problem with gfortran and named pipes under unix

[Johannes Lotz]

Hello.

I have a problem using gfortran for a code dealing with named pipes.
In the attachement is a small example for that (bigger than necessary, 
because of copy/paste from the original code).

It just forks the program, opens the named pipe and writes some stuff to it.
I tried compiling with ifort (intel), and the problem was gone.

Any idea, where the problem comes from? I think gfortran does not open 
the pipe correctly (~O_NONBLOCK already tried).

Thanks,
 johannes
