Dear all,
the attached patch is the result of my attempts to fix an ICE when
compiling gfortran.dg/proc_ptr_52.f90 with -fcheck=all. While
trying to reduce this, I found several oddities with functions
returning class(*), pointer that ICE'd too.
The original ICE in the PR turned out to be a bug in the pointer
checking code when passing a procedure pointer to a CLASS procedure
dummy that tried to access the container of the procedure pointer.
I believe that this should not be done, and one should only check
that the procedure pointer is not null.
I am not too experienced which class-valued functions, so if any
of the experts (Paul, Andre', ...) could have a look?
(After fixing the issue with -fcheck=pointer, I ran into a bogus
error with -Wexternal-argument-mismatch for the same testcase.
This is now pr119928.)
Regtested on x86_64-pc-linux-gnu. OK for mainline?
Cheers,
Harald
OK Harald,
