------- Comment #2 from jvdelisle at gcc dot gnu dot org 2007-06-06 01:59 -------
The problem is here in resolve.c:
static int
generic_sym (gfc_symbol *sym)
{
gfc_symbol *s;
if (sym->attr.generic ||
(sym->attr.intrinsic && gfc_generic_intrinsic (sym->name)))
return 1;
if (was_declared (sym) || sym->ns->parent == NULL)
return 0;
gfc_find_symbol (sym->name, sym->ns->parent, 1, &s);
return (s == NULL) ? 0 : generic_sym (s);
}
gfc_find_symbol is returning the same symbol that is called with generic_sym
and thus we are in an infinite loop, calling genric_sym with that same symbol
over and over again.
I think this is related to 32157. gfortran does not discriminate symbols of
the same name but with different scope or type.

This ICEs as well:
MODULE ksbin1_aux_mod
interface foo
module procedure k
end interface
CONTAINS
FUNCTION j ()
j = 1
ENTRY k ()
k = 2
END FUNCTION j
END MODULE ksbin1_aux_mod
I thought that such things had been fixed a while since *sigh*

This fixes the infinite recursive loop and fixes a segfault I was getting on
the original test case. The test case in comment #8 is something different.

Example of bad translation
This attached example of tree-dump-original shows that we are getting a
translation error. See the k=2B . It should be k.1 = 2. So the error is
after my initial patch with test case in #8:
pr31609-2.f90:11: internal compiler error: gimplification failed
Getting closer I hope
