Originally reported on Google Code with ID 129

.. because the call does not have the noreturn attribute in the LLVM IR. 

define void @_Z3fooPPv(i8** %b) noreturn nounwind uwtable {
entry:
  %0 = bitcast i8** %b to i8*
  tail call void @llvm.eh.sjlj.longjmp(i8* %0)   <<<<<<<<<<<<<
  unreachable
}

declare void @llvm.eh.sjlj.longjmp(i8*) noreturn nounwind
