This then looks like a bug in clang/libobjc2 to me. I went through the 
output file you send me from compiling with clang and there were a few 
bugs detected, which I am going to fix later today, but none of them 
would justify the results you are getting. Most of them are printf 
format errors. It is great that clang pays extra attention here.

You could try to use a different combination of runtime and compiler to 
narrow down the real culprit. Not sure whether gcc + libobjc2 or clang + 
libobjc are supposed to work.
