I assume that this is a bug in the new parser....

temporary.cxx:
--------------
template<int foo>
struct A1 {
    A1(int, int, int) {}
};

template<int foo>
struct A2 {
    A2(int, int) {}
};

template<int foo>
struct B {
    int b;
    void bar1() { A1<foo>(b, b, b); }
    void bar2() { A2<foo>(b, b); }
    void bar3() { A1<foo> a1(b, b, b); }
};
--------------

% gcc34 -c temporary.cxx
temporary.cxx: In member function `void B<foo>::bar1()':
temporary.cxx:14: error: expected init-declarator
temporary.cxx:14: error: expected `,' or `;'

bar2() [ not as many constructor arguments ] and bar3() [using an explicit temporary] work.

bar1() also works in gcc-3.3/gcc-3.2 and gcc-3.4 prior to the new parser merge.

I also tried the online Comeau-C++ compiler and Intel icc-7.0 and they both accepted the code as well.
