--- Comment #3 from simon at pushface dot org --- I just rebuilt r269886 on x86_64-apple-darwin15 (with --disable-bootstrap) and it passed: PASS: gnat.dg/socket2.adb (test for excess errors) PASS: gnat.dg/socket2.adb execution test Also, running just that test with that compiler on an x64_64-apple-darwin18 machine succeeded.
