[Bug c++/36430] New: Cannot convert a temporary to a non-const reference even with conversion operator

[gbrammer at gmx dot de]

struct Foo {
    operator Foo & () { return *this; }
};
void frobnicate(Foo &) {
/* in reality, the Foo is changed here and returned */
}
int main () {
    frobnicate (Foo());
}

temporary.cpp:8: error: invalid initialization of non-const reference of type
‘Foo&’ from a temporary of type ‘Foo’
temporary.cpp:4: error: in passing argument 1 of ‘void frobnicate(Foo&)’

This works with g++ 4.1, but does not work with 4.2 and 4.3.
