  [/var/tmp/llvm/llvm/llvm/tools/clang/lib/Analysis/UninitializedValues.cpp :
172:56] D.147621 ={v} {CLOBBER};
  [/var/tmp/llvm/llvm/llvm/include/llvm/ADT/PointerIntPair.h : 69:73]
D.176111_21 = MEM[(const struct PointerIntPair
*)[/var/tmp/llvm/llvm/llvm/tools/clang/lib/Analysis/UninitializedValues.cpp :
172] &D.147621].Value;

That is obviously broken.
