Bug #: 52909
Summary: Procedure pointers not private to modules
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: aben...@caltech.edu
The following code won't compile with the latest gfortran (or with 4.6 and
4.7). The two procedure pointers should be private to their respective modules
so there should be no symbol conflict.
module Module1
implicit none
private
procedure(), pointer :: procPtr => null()
end module Module1
module Module2
implicit none
private
procedure(), pointer :: procPtr => null()
end module Module2
program Test
use Module1
use Module2
implicit none
end program Test
$ gfortran -v
Using built-in specs.
