error not detected unless -warn all is given

Hi all,

I am debugging a friend's code. At some point he calls a subroutine with the wrong number of arguments, actually he gives more actual arguments than dummy ones. I didn't spot the error until I used the -warn all option to compile. Is this the expected behaviour?

The -warn all option

The -warn all option generates interfaces and checks interfaces. The Fortran compiler cannot verify calling arguments for subroutines and functions that do not have/use interfaces. Subroutines and functions contained in modules have interfaces by default, Those non-module subroutines and functions do not have interfaces (though some checking could potentially be performed in the IPO phase).
