Fortran code showing problem

Hi All!

Due to the way deferred character length is implemented, using SAVE_EXPR, it
will usually contain garbage.

Seen on: 

GNU Fortran (GCC) 9.3.1 20210526
GNU Fortran (GCC) 10.3.1 20210526
GNU Fortran (GCC) 11.1.1 20210526
GNU Fortran (GCC) 12.0.0 20210527 (experimental)

Thank you very much.

Best regards,
José Rui
