gcc-ss-20010514 bootstrap failure on ia64


The stage1 compiler in gcc-ss-20010514 miscompiles at least rtl.c, which
causes gencodes to crash.  I have added some debugging prints and get this
output:

read_rtx: define_attr
s
0x600000000000c8f0 "itanium_class"
s
0x600000000000c8f0 "itanium_class"
read_rtx: const_string
s
0x600000000000c8f0 "itanium_class"
(const_string ("itanium_class"))
(define_attr ("itanium_class") ("itanium_class")
    (const_string ("itanium_class")))

As you can see, obstack_finish is always returning the same pointer.
rtl_obstack.object_base is never set to rtl_obstack.next_free.

Andreas.
