Subject: Re: [4.1 Regression]
23_containers/vector/bool/6886.cc fails
This really shouldn't be mine -- faults in dominance.c aren't something
I'm likely going to be able to fix as I'm not that familiar with with
the code we have to compute and update the dominator tree.

It was almost certain introduced by:
2005-07-06 Jeff Law <law@redhat.com>
* tree-ssa-dce.c (cfg_altered): New global.
(tree_dce_init): Initialize cfg_altered.
(remove_dead_stmt): If we remove an edge in the CFG, then set
CFG_ALTERED.
(perform_tree_ssa_dce): If we altered the CFG, then invalidate
the dominators.

Created an attachment (id=9221)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=9221&action=view)
a little reduced testcase
I removed a lot of the unneeded code but I don't have time to finish this right
now (and I was getting bored reducing it by hand).
