Bug ID: 92736
Summary: Error when using a variable from a module in a
submodule and its parent module.
Product: gcc
Version: 9.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: chinoune.mehdi at hotmail dot com
Target Milestone: ---
gfortran recently start to reject this code :
module m1
implicit none
integer, parameter :: i = 10
end module m1
module m2
use m1, only : i
implicit none
interface
module subroutine sb1()
end subroutine sb1
end interface
end module m2
submodule(m2) s1
use m1, only : i
implicit none
contains
module subroutine sb1
print*,"hello"
end subroutine sb1
end submodule s1
gfortran-9 -c file.f90
15 | submodule(m2) s1
| 1
16 | use m1, only : i
| 2
Error:
Symbol ‘i’ at (1) conflicts with the symbol at (2)
The error message is not clear!
I can compile it using gfortran 8.3.0 and 9.2.0, but it fails with 9.2.1 and
10.0
I think this is where it started failing :
