--- Comment #10 from Joakim <db...@joakim.fea.st> --- I ran into this on Android/ARM too, with ldc. As the linked ldc comment and Jacob note, this is an incompatibility in the way clang and gcc work with empty structs on every platform, whether Linux/x86 or Android/ARM. This test and the auto-tester simply use gcc on every other tested platform, while clang is the system compiler on OS X now. --
