Bug ID: 61615
Summary: Failure to resolve correct generic with TYPE(C_PTR)
arguments
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: thatcadguy at gmail dot com
The following program does not produce the expected output (the line 'CALL
bar(a, b)' does not choose the subroutine bar_s as it should, it chooses
bar_a1d):
MODULE foo
USE iso_c_binding
IMPLICIT NONE
INTERFACE bar
MODULE PROCEDURE bar_s
MODULE PROCEDURE bar_a1d
END INTERFACE bar
CONTAINS
SUBROUTINE bar_s(a, b)
TYPE(c_ptr) :: a, b
WRITE (0, *) 'in bar_s'
END SUBROUTINE bar_s
SUBROUTINE bar_a1d(a, b)
TYPE(c_ptr) :: a(:), b(:)
WRITE (0, *) 'in bar_a1d'
END SUBROUTINE bar_a1d
END MODULE foo
PROGRAM cptr_array_vs_scalar_arg
USE foo
USE iso_c_binding
IMPLICIT NONE
INTEGER, TARGET :: i
TYPE(c_ptr) :: a, b
a = C_LOC(i)
b = C_LOC(i)
CALL bar(a, b)
END PROGRAM cptr_array_vs_scalar_arg
