------- Comment #2 from burnus at gcc dot gnu dot org 2009-05-06 14:39 -------
Regarding the segfault, valgrind shows:
==14376== Invalid read of size 1
==14376== by 0x616A4F7: fprintf (in /lib64/libc-2.9.so)
==14376== by 0x4B4BF1: show_typebound (dump-parse-tree.c:693)
The line is:
fprintf (dumpfile, "PASS(%s)", st->n.tb->pass_arg);
and the interesting question is: Why is it called? There are no type-bound
procedures (and also no components [except of t2%t]. Thus why is
if (!st->n.tb)
return;
not working?
* * *
Related problem: The following gives: show_code_node(): Bad statement code
type t
procedure(), nopass, pointer :: p
end type t
type(t) m
!external bar
!m%p => bar
call m%p()
end

If it's a regression it may be caused by Daniel's r146733 ("reworking
type-bound procedures")?!?
> Related problem: The following gives: show_code_node(): Bad statement code
I will handle this in my PPC patch before committing.

------- Comment #4 from domob at gcc dot gnu dot org 2009-05-06 15:01 -------
Yes, that sounds like a problem caused by my patch; it did change the structure
of storing the type-bounds, so maybe simply changing the if to the one shown by
Tobias was wrong.
I will look into this!

Fixed (not addressing the "related" part in comment #2, but Janus promised to
work on it).
