[Bug c++/38007] [4.2/4.3/4.4 Regression] g++ instantiate same operator twice due to bitfield in -O0 mode, causing symbol already defined assembler error

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2008-11-03 20:07 -------
Confirmed, a regression from GCC 4.1.1.
Here is a self contained example :):
class foo {
    public:
        template <typename T> operator T ();
};

template <typename T>
    inline foo::operator T () {
        return (T)0;
    }

struct bar {
    unsigned int _bar : 24;
};

int main() {
    foo a;
    unsigned int b = a;
    bar c;
    c._bar = a;
    return 1;
}
