------- Comment #1 from burnus at gcc dot gnu dot org 2007-07-19 08:30 ------- For the accept-invalid part (c_loc of an assumed-shape array). The standard says: "X shall either (1) have interoperable type and type parameters and be (a) a variable that has the TARGET attribute and is interoperable,"
This variable has the TARGET attribute, but is not interoperable: "An array Fortran variable is interoperable if its type and type parameters are interoperable and it is of explicit shape or assumed size." Thus this error by NAG f95 is ok; however, as it is accepted by ifort, g95 and (currently) gfortran. As I completely fail to see any valid use of it and see several cases where it seems to work but one uses in reality the wrong array element, I favour to not allowing it even for -std=gnu. But if one finds a valid use, I'm also fine with an error only for -std=f2003. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32804
