From: "giovannibajo at libero dot it" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/13478] [3.3/3.4 Regression] gcc uses wrong constructor to initialize a const reference Date: Sun, 11 Jan 2004 12:24:00 -0000 [thread overview] Message-ID: <20040111122454.31306.qmail@sources.redhat.com> (raw) In-Reply-To: <20031223143303.13478.erich_guenther@hotmail.com> ------- Additional Comments From giovannibajo at libero dot it 2004-01-11 12:24 ------- Ok. Given: ------------------------------------ struct A {}; struct B : protected A { B() {}; B(const A& ) {}; private: B(const B& ) {}; }; void foo(const A* ap) { const B& br = *ap; } ------------------------------------ The code should compile, because it should call B(const A&) to construct the temporary which is then bound to the const reference. Instead, GCC seems to call B(const B&), which is private. I can't test on 3.0/3.1, but it's surely a regression since 3.0.4, and can be made a wrong-code one if we make the constructor public. I keep it as rejects-valid as it's easier to debug. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |giovannibajo at libero dot | |it Status|UNCONFIRMED |NEW Ever Confirmed| |1 Keywords| |rejects-valid Last reconfirmed|0000-00-00 00:00:00 |2004-01-11 12:24:53 date| | Summary|gcc uses wrong constructor |[3.3/3.4 Regression] gcc |to initialize a const |uses wrong constructor to |reference |initialize a const reference Target Milestone|--- |3.4.0 Version|3.3 |3.4.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13478
