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.
