This one is actually a 4.6 and 4.7 regression. It runs fine on 4.3, 4.4 and
4.5. Reduced testcase:
module m
type int
integer :: val
end type int
contains
type(int) function foo()
foo%val = 42
end function foo
end module m
program p
use m
print *, foo()
end program p

--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-11-24 22:13:06 UTC ---
That a -fwhole-file regression, which became the default in 4.6. The work
around is -fno-whole-file.
The problem is in gfc_get_extern_function_decl:
gfc_find_symbol (sym->name, gsym->ns, 0, &s);
if (s && s->backend_decl)
{
sym->backend_decl = s->backend_decl;
return sym->backend_decl;
}
The problem is that this does not set
sym->ts.u.derived{,->components{,->next}}->backend_decl
for BT_DERIVED/BT_CLASS; one might also need to update
sym->ts.u.cl...
for BT_CHARACTER.
Note: There are more places in trans*.c which call gfc_find_gsymbol

Patch for this issue - note that there are more places which have to be checked
and potentially fixed. The second part is just a performance/algorithmic
optimization, which occurs in real code.
