Created an attachment (id=12591)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=12591&action=view)
patch to fix the out of ssa bug exposed when PRE/FRE are turned off.
That would fix it, but its safer for future changes to simply check if the
annotation exists right in var_to_partition rather than at a single instance.
I'll check this in shortly
