Hi Harald, I ran also the same with gfortran v11.2. together with singularity and
did not work as well. Then i change the defintion of the buffer size in unix.c to default at 1 MiB and it works. What do you mean by vendor? Do you think the problem could be linked to running fortran within singularity container?

I'm afraid you need to contact your vendor or system folks. Cheers, Harald Gesendet: Mittwoch, 23.
