Bug ID: 99982
Summary: INTERFACE selects wrong module procedure involving
C_PTR and C_FUNPTR
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: brtnfld at hdfgroup dot org
Target Milestone: ---
Created attachment 50532
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50532&action=edit
program uses interface and module procedure to select between subroutines with
type C_PTR and C_FUNPTR
The attached program always selects the TYPE(C_FUNPTR) when selecting between a
(overloaded) subroutine with TYPE(C_PTR) and TYPE(C_FUNPTR), even when the
variable type is TYPE(C_PTR).
It does this for both passing a variable as the argument or using the C_LOC or
c_funloc directly in the call.
I tried it with 7.5.0, 10.2.0, same behavior.
Intel and NAG both select the correct subroutine.

I checked with gcc master (4/20/2021), and it still has the same issue.

I noticed the problem when building CGNS with gfortran / Gcc 10.2.0, and now
with Gcc 10.3.2 the issue disappeared.

No. The reported problem still exists. Output for the attached testcase:
cg_configure_funptr
cg_configure_funptr
cg_configure_funptr
cg_configure_funptr
Expected:
cg_configure_ptr
cg_configure_funptr
cg_configure_ptr
cg_configure_funptr

Is there an update on this issue, the CGNS fortran wrappers will not work with
gfortran as there are no work arounds for this issue.
Thanks.

I removed the c_funptr interface in CGNS since it was not being used.

--- Comment #11 from Scot Breitenfeld <brtnfld at hdfgroup dot org> ---
Thanks for the standard reference. That is indeed what I was looking for. I
understand now that, in this case, the INTENT refers to whether C_PTR can be
changed and does not relate to the INTENT state of the target. I should change
all my usage cases to INTENT(IN) since none of the Fortran wrappers allow
changes to the pointer itself.
