Perhaps, something along the lines of -fallow-invalid-boz I recently introduced. Issue an error be default, but have -fallow-argument-mismatch downgrades the error to a warning. The only way to disable the warning is with -w. Personally, if gfortran can detect an error in code, I think it should report the error to the user. -- Steve
