[Bug libgcj/15813] New: Throw_2 test case does not work anymore.

["andreast at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The Throw_2 test case from the libjava suite fails since the patch from 
> 2004-05-19  Jeff Law <law@redhat.com>
>  * tree-into-ssa.c (prepare_operand_for_rename): New argument
> 	is_use.
>          If the operand is for a use, then strip away the SSA_NAME, do
>   	not strip away the SSA_NAME for a set.  Never call
> 	release_ssa_name.
>          (mark_def_sites): Appropriately pass additional argument to
>          prepare_operand_for_rename.  If a VDEF_RESULT is not an

>          (set_def_block): Strip away any SSA_NAME to get to the real

I have the feeling that something gets miscompiled in the area of boehm-gc.
My tests so far show that just before the patch it works and afterwards the test
case times out. A comparison of the libgcj.a shows some differences in a few
files. I will post the file names soon. One is finalize.o from boehm-gc. This
bug is maybe related to 15812?
