--- Comment #6 from vmorgulys at gmail dot com --- Hello Jonathan, I have another similar issue with auto and deleted contructrors ("=delete"). They are not detected at compile time. Do you think it is related to what you mention in your comment (Concept TS)? If I understand correctly, I need to build gcc with the trunk version to be sure. Is it correct? Thank you a lot for your work on gcc.
