The expr evaluator claims printf("Hello\n") returns 0, but it should return 6. This was tracked as rdar://24599697 and mistakenly closed, it seems.

The problem is to be that we end up calling the member "printf" function instead of the extern "C" version. D70846/a705cf1ac fixes that for the case of "manual" dwarf index.
