From: "niemayer at isg dot de" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/15076] cast to void * of parameter in call to template constructor causes compilation error Date: Thu, 22 Apr 2004 20:21:00 -0000 [thread overview] Message-ID: <20040422184040.14379.qmail@sources.redhat.com> (raw) In-Reply-To: <20040422183522.15076.niemayer@isg.de> ------- Additional Comments From niemayer at isg dot de 2004-04-22 18:40 ------- Just noticed that the sample code can be made even simpler, the second class isn't necessary: ------------------------------------------------------------------------------- class X { public: void * v; X(void * v_) : v(v_) { } }; template <class T> class Y : public T { public: template <typename X1> Y(X1 & x1) : T(x1) { } }; void test(void) { void * v = (void *)123; Y<X> * y1 = new Y<X>(v); // works Y<X> * y3 = new Y<X>(reinterpret_cast<void *>(v)); // works Y<X> * y2 = new Y<X>((void *)v); // error - why?? } ------------------------------------------------------------------------------ -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15076
