Diego,

it looks like it's this change:

+2005-05-10  Diego Novillo  <dnovillo@redhat.com>
+
+       * tree-optimize.c (init_tree_optimization_passes): Re-organize
+       optimization passes to do an initial batch of scalar cleanups.
+

which is rather unfortunate since this means we have some kind of
miscompilation.

Can you try bootstrapping with Ada included on x86-64 or ppc and does
this work for you?
