This is failing when allocating the registers.
Seems like there are a large number of code in this function.

Well, yes, but it worked on June 19 when I filed this unrelated bug

With commands like this:
cvs update -D "July 22, 2004"
I found that the example program compiled on July 20 and didn't on July 24.
Bootstrap failed on July 22.
I'll work on this more later.

Hmm, the only thing major that went into between those days were Deigo's aliasing changes (and
some cleanups which should not have any effect on code generation at all).
Which was:
2004-07-22 Diego Novillo <dnovillo@redhat.com>
* tree-into-ssa.c (set_livein_block): Fix typo in comment.
(rewrite_ssa_into_ssa): Start iterating over SSA names at 1.
Release SSA names that have been re-renamed.
....
