example
If you malloc() a buffer and pass it to -[NSData initWithBytesNoCopy:length:],
clang-sa realizes that the method takes the responsibility of calling free().
If you later call free() on that buffer, clang-sa should warn about a
double-free().
clang version 3.2 (trunk 156620)
Target: x86_64-apple-darwin11.3.0
