--- Comment #3 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Maxim Ostapenko from comment #1) > Eh, mine. > > typedef void (^os_trace_payload_t)(xpc_object_t xdict) looks very strange, > it seems that it's an Objective-C declaration, right? It's declaring os_trace_payload_t to of type "Apple block" (like a lambda that can be used over the whole of c-family); Apple blocks are currently not supported by GCC. There is no realistic work-around, any interface using blocks will fail, and thus either those interfaces need to be excluded from tests, or the tests skipped/xfailed. > > Could you check: > > 1) Libc version on your system. > 2) Contents of /usr/include/os/trace.h. Is that a valid C header?
