This is not a cryptic error, but an internal error which means that some expectation of the compiler didn't hold up. Since the numbers of internal errors are unique their location is easily to pinpoint. In that regard they are the best kind of errors ;) Regarding your problem at hand: forward declarations of generics are not supported. Regards, Sven |

Yeah, I've found this error by grepping, but resulting condition wasn't less cryptic to me :). Are there any workaround for the above case? I'm writing an interface to C++ library which heavy uses such declarations and the only solution found was to use generic pointers instead of forward declarations. |

I'm resolving this as a duplicate for the younger one as that has a potential patch attached. |
