FYI, the x86_64-apple-darwin12 testsuite results with the proposed patch are at... http://gcc.gnu.org/ml/gcc-testresults/2012-10/msg00434.html It appears that the patch should also special case the "scan-assembler \\\\.internal.*Foo.methodEv" tests in g++.dg/ext/visibility/pragma-override1.C and g++.dg/ext/visibility/pragma-override2.C on darwin as well... FAIL: g++.dg/ext/visibility/pragma-override1.C -std=c++98 scan-assembler \\\\.internal.*Foo.methodEv FAIL: g++.dg/ext/visibility/pragma-override1.C -std=c++11 scan-assembler \\\\.internal.*Foo.methodEv FAIL: g++.dg/ext/visibility/pragma-override2.C -std=c++98 scan-assembler \\\\.internal.*Foo.methodEv FAIL: g++.dg/ext/visibility/pragma-override2.C -std=c++11 scan-assembler \\\\.internal.*Foo.methodEv Jack
