------- Comment #3 from burnus at gcc dot gnu dot org 2008-12-30 16:50 -------
Works with 4.2.1 (x86_64-suse-linux). Valgrind shows:
==27337== Invalid read of size 1
==27337== at 0x4752E2: resolve_symbol (resolve.c:9311)
==27337== by 0x482726: traverse_ns (symbol.c:3127)
==27337== by 0x482715: traverse_ns (symbol.c:3124)
==27337== by 0x482715: traverse_ns (symbol.c:3124)
==27337== by 0x470A3F: resolve_types (resolve.c:10428)
That seems to be:
if (sym->ts.type == BT_DERIVED
&& sym->ts.derived->attr.use_assoc
&& sym->ns->proc_name->attr.flavor == FL_MODULE)
The problem is that for sym->name == "pdm_bps":
(gdb) p sym->ts.type
$3 = BT_DERIVED
(gdb) p sym->ts.derived->attr.use_assoc
$4 = 1
(gdb) p sym->ns->proc_name
$5 = (struct gfc_symbol *) 0x0
Thus there is no surprise that sym->ns->proc_name->attr.flavor gives an ICE.
Note:
(gdb) p sym->attr.flavor
$7 = FL_VARIABLE

* resolve.c (resolve_structure_cons): It is an error to assign
NULL to anything other than a pointer or allocatable component.
PR fortran/33295
* resolve.c (resolve_symbol): If the symbol is a derived type,
resolve the derived type. If the symbol is a derived type
function, ensure that the derived type is visible in the same
namespace as the function.
