Different root vars: checker$ptr and p across an abnormal edge from BB3->BB6 
t.cc: In function `void pipe()': 
t.cc:25466: internal compiler error: SSA corruption 
 
The test case, which I'll attach soon, comes from aspell.  I've tried 
to reduce the test case to something manageable, though probably some 
more C++-savvy bug master can reduce it a lot further...
