* [Bug fortran/40591] New: Procedure(interface): Rejected if interface is indirectly hostassociated

The following program fails with:
procedure(sub), pointer :: pptr2
1
Error: Interface 'sub' of procedure 'pptr2' at (1) must be explicit
The question is whether it is valid or not. As both NAG f95 and ifort reject it
(g95 accepts it), it might be invalid.
However, if one uncomments pptr1: gfortran, NAG f95 and g95 accept pptr1 and
pptr2 -- while ifort continues to reject pptr2 only. Thus it might be valid at
the end.
program main
! procedure(sub), pointer :: pptr1
! nullify (pptr1)
contains
subroutine test()
procedure(sub), pointer :: pptr2
nullify (pptr2)
end subroutine test
subroutine sub()
end subroutine sub
end program main

Although I can find nowhere in the standards that says that it is valid, I
believe that by the normal rules of host association of procedures, it must be.
gfortran accepts it if 'test' and 'sub' are interchanged.
I have put it on my todo list.
Cheers

Well..... I suppose that I should accept the bug :-)
I will commit the fix to 4.4 over the weekend, so please try to test it to
destruction on 4.5.

It seems that gfortran.dg/proc_ptr_21.f90 is failing on i686-pc-linux-gnu and
Intel64(?), see

I can - somewhat - reproduce it. It does not fail but valgrind shows
(x86-64-linux and i686-linux):
==32231== Conditional jump or move depends on uninitialised value(s)
==32231== at 0x80485A2: test.1513 (proc_ptr_21.f90:26)
==32231== by 0x8048548: MAIN__ (proc_ptr_21.f90:8)
==32231== by 0x80485F4: main (proc_ptr_21.f90:8)
That is solved by adding:
i = 0
to subroutine test (while any other number causes the abortion).

Indeed - that was in the test originally; I do not know what happened to it.
I'll put it right tonight.
Thanks

Note that I did not apply the patch to 4.4 as I said that I would. What do you
think?

4.4 is sufficiently different from 4.5/6 that I am closing this as fixed.
