This is a side effect of not pre-splitting critical edges.
If you change the #if 0 code in tree-ssa-pre.c's split_critical_edges to #if 1, the test case compiles 
fine.

ENabling this code is currently blocked on another bug in edge splitting/edge insertion, but as 
soon as that is cleared up, this will be fixed.
