Does not happen with -O2 either:
: Search converges between 2003-10-12-ssa (#106) and 2003-10-13-ssa (#107).

The original test case also hast this ICE at -O2, I can provide it if anybody
is interested.

Interesting.  We are exposing new symbols after the second DOM pass.  If you
replace the call to abort() at tree-optimize.c:163 with the line below, it
should work.  However, I'd like to take a look at the test case and see why
weren't all the symbols exposed by the 1st DOM and CCP passes.

rewrite_into_ssa (fndecl, vars_to_rename, TDI_ssa_5);

I'll take this PR.

Fixed by running SSA renamer after DOM2.
