Bug ID: 102992 Summary: Piping in a file does no longer work on macOS Monterey Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: juergen.reuter at desy dot de Target Milestone: --- I don't know whether this is really an issue with gfortran or a screwed setting of my macOS installation, I have macOS 12.0.1 Monterey, Darwin 21.1.0, with XCode 13.1, and a simple file main.f90: program main print *, "42" end program main gfortran -o conftest main.f90 prints 42 in the shell, so to stdout. But when tryng pipe to a file this does not work, the file is always empty, i.e. ./conftest > bla.txt result in an empty file.
