Package: g++-4.0
Version: 4.0.3-1
Severity: normal

g++ compiles the following wrong C++ code without complaining:

   #include <complex>
   class A {
   public:
      A() {}
   };

   int main()
   {
      std::complex<double> bla(bla);
      A blubb(blubb);
   }

This bug also affects g++-3.4. g++-3.3 correctly complaints:

test.cc: In function `int main()':
test.cc:12: error: `bla' undeclared (first use this function)
test.cc:12: error: (Each undeclared identifier is reported only once for
                each
                   function it appears in.)
test.cc:13: error: `a' undeclared (first use this function)
