I noticed that we don't implement [basic.lookup.argdep]/3: quite correctly; it says "If X (the lookup set produced by unqualified lookup) contains -- a block-scope function declaration that is not a using-declaration [...] then Y (the lookup set produced by ADL) is empty." but we were still performing ADL in fn1 in the attached test. The problem was that we were only looking at the first function in the overload set which in this case happened to be a using-declaration, and those don't suppress ADL. We have to look through the whole set to find out if unqualified lookup found a block-scope function declaration, or a member function declaration.Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk? PR c++/95074 * parser.c (cp_parser_postfix_expression) <case CPP_OPEN_PAREN>: When looking for a block-scope function declaration, look through the whole set, not just the first function in the overload set.
ok, thanks! -- Nathan Sidwell
