; Test for a problem afflicting several C++ programs in the testsuite.  The 
; instcombine pass is trying to get rid of the cast in the invoke instruction, 
; inserting a cast of the return value after the PHI instruction, but which is
; used by the PHI instruction.  This is bad: because of the semantics of the
; invoke instruction, we really cannot perform this transformation at all at
; least without splitting the critical edge.
