the following code doesn't compile with gcc 3.2.3:

class Foo {
      Foo():m_i(0) {}
      Foo(int i):m_i(i) {}
       int m_i;

class Bar {
      Bar(const Foo& foo):m_k(0) {}
      Bar(const Foo& foo, int k):m_k(k) {}
      int m_k;

int main() {
   Bar bar(Foo(), 1);
//   Bar bar((const Foo&)Foo(), 1); //works, more typing
//   Bar bar(*&Foo(), 1);           // works, but is ugly
//   Bar bar(Foo(0), 1);            // works, but is something different
//   Bar bar(Foo());                // works, but is something different

When trying to compile this with gcc 3.2.3 it gives:

~/src/ctorproblem$ g++ -Wall main.cpp -o ctorproblem
main.cpp: In function `int main()':
main.cpp:20: type specifier omitted for parameter
main.cpp:20: syntax error before numeric constant

This is the same issue we have in svn in several places, e.g. here:

What should we do about this ?
Which versions of gcc are able to compile this ?
