(-fdump-ipa-reference should > show "read-only var OBJC_CLASS_REFERENCES_0" if that is the problem) -fdump-ipa-reference - is unrecognized on my build - do I need a config. option to enable? -fdump-ipa-all doesn't seem to give a file named as reference... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43061
