The following code fails to compile on both GCC 7.1 and trunk: ``` auto nop = [] (auto&& ...) {}; int main() { nop(); } ``` Live demo: https://wandbox.org/permlink/XNh0JqswieVsAeb0 Clang accepts it: https://wandbox.org/permlink/0Jys6k7mx8Wa29yK `std::invoke(nop)` fails to compile as well, I'm not sure if the cause is the same: https://wandbox.org/permlink/kTU9YnRhSodSoHEP (The error message seems to be truncated some way, both on wandbox and my Linux box..)
This is bug 64095.
Indeed, thanks, Tim. *** This bug has been marked as a duplicate of bug 64095 ***
