Hi,

I can confirm that I don’t see this failure on a Debian bullseye/sid (Linux 5.11.0-46, glibc 2.31-0ubuntu9.2) with a fresh bootstrap of master:

$ grep signaling testsuite/gfortran/gfortran.sum
PASS: gfortran.dg/ieee/signaling_1.f90   -O0  (test for excess errors)
PASS: gfortran.dg/ieee/signaling_1.f90   -O0  execution test

It’s showing on some gcc-testresults for x86_64 and aarch64 linux, so I’ll need someone (HJ, Andreas are in CC) to show me what the error is.

It may be related to the use of dg-options instead of dg-additional-options in that testcase, so I pushed the attached fix. I’ll check the test results mailing-list to see if it improved things (or confirm when the error message is posted).

    Fortran: fix testcase compiler flags
    
    -fsignaling-nans is already passed by ieee.exp, so it's not needed.
    We must use dg-additional-options instead of dg-options, otherwise we
    override flags passed from ieee.exp. And we need to use -w because
    some options only make sense for the Fortran source.
    
    gcc/testsuite/ChangeLog:
    
            * gfortran.dg/ieee/signaling_1.f90: Adjust flags.
