Summary: generic interface to external function in module Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: mh...@gmx.at Created attachment 23650 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23650 test case Compiling the Fortran module module module_m interface test function test1( ) result( test ) integer :: test end function test1 end interface test end module module_m with gfortran-4.6.0 leads to an internal compiler error. The error occurs because the name of the result variable is equal to the generic name. If the same interface is in a Fortran program no error occurs. $ gfortran-4.6 -v -c module_m.f90 Using built-in specs.
