--- Comment #4 from john.harper at vuw dot ac.nz --- Sorry if I did something wrong when installing gfortran 15 from source tarball gcc-15.1.0.tar.xz in a Linux Ubuntu system. Maybe your gfortran 15 is not identical to the release I used. I certainly don't know how to fake gfortran --version and I didn't want to. My evidence: (lf) john:~$ ls -o Downloads/gcc-15.1.0.tar.xz -rw-rw-r-- 1 john 98268344 Apr 30 11:31 Downloads/gcc-15.1.0.tar.xz (lf) john:~$ cat badfmt.f90 ! F2023 constraint C1302 requires a comma between A and I in a format character(5):: fmt = '(AI0)' print fmt, '6*7 = ',42 end program (lf) john:~$ gfortran --version GNU Fortran (GCC) 15.1.0 Copyright (C) 2025 Free Software Foundation, Inc.
