"A a(int(x));" declares an object and calls a constructor, but is parsed as if it were "A a(int x);" which declares a function pointer. Date: Tue, 17 Aug 2004 09:40:00 -0000 [thread overview] Message-ID: <20040817094023.17061.andrei.mischenko@mail.ru> (raw) c++ syntax analyser bug. "A a(int(x));" declares an object and calls a cast operator and constructor, but is parsed as if it were "A a(int x);" which declares a function pointer.Thus the compiler forbids the feather legal usage of an object "a".
