Summary: Double colon in procedure-stmt (generic interface) Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: eh.toussa...@gmail.com In Fortran 2008 the (module) procedure statement in a generic interface can contain a double colon, according to R1206: R1206 procedure-stmt is [ MODULE ] PROCEDURE [ :: ] procedure-name-list When I try to compile the following module with gfortran 4.7-20110423 I get an error. module m1 implicit none interface foo module procedure :: bar end interface contains subroutine bar end subroutine end module $ gfortran -c -std=f2008 m1.f90 m1.f90:4.23: module procedure :: bar 1 Error: Syntax error in MODULE PROCEDURE statement at (1) (The '1' indicates the double colon as the location of the error.) If I remove the double colon the file compiles without error - which is expected, as the optional double colon didn't appear in the rule in previous versions of the standard. $ gcc -v Using built-in specs.
