bug: exceptions thrown during CI

[gnikit]

Our CI tests throw multiple exceptions, here is the first instance https://github.com/pseewald/fprettify/runs/8113952328?check_suite_focus=true#step:6:85 but if you scroll down you will find more. This issue can be replicated locally as well.

Sorry for the late reply. These exceptions are expected failures, see output at the bottom:

IGNORED errors: invalid or old Fortran
----------------------------------------------------------------------
parse errors:       4     
internal errors:    13

But I agree that the error output should be suppressed in those cases, so I'll leave this open.
