full 64 bit bootstrap is now failing:

r161941 ko

| Storage_Error stack overflow (or erroneous memory access) |

Then at r162274 there's a new earlier failure in bootstrap, probably masking
the above:

------- Comment #3 from ebotcazou at gcc dot gnu dot org 2010-07-27 20:15 -------
Introduced by the fix for PR middle-end/44790:
2010-07-07 Richard Guenther <rguenther@suse.de>
PR middle-end/44790
* expr.c (expand_expr_real_1): Go the POINTER_PLUS_EXPR path
for expanding the constant offset for MEM_REFs.
The problem is that:
name = MEM[(struct
exp_ch3__make_predefined_primitive_specs__B_99__stream_op_tss_names___PAD
*)D.14526_1156 + 4294967296B];
is expanded into
sethi %hi(stream_op_tss_names.6060+4294967296), %l2
or %l2, %lo(stream_op_tss_names.6060+4294967296), %l2
which overflows since sethi is a 32-bit operator.
Going through POINTER_PLUS_EXPR to expand a const addresss apparently bypasses
checks for valid addresses in the back-end.
