After more hunting, it appears the bug is caused by clang not NULL-terminating
the class name string, resulting in the class lookup failing and the resulting
0 being propagated upwards.  LLVM is therefore working as expected.  The reason
adding extra code to the function caused it to work is that it, presumably,
moved the alignment of things around so that the class string was followed by a
null byte.
