--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-04-28 10:02:39 UTC --- [/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.
