[Bug c++/14967] New: [3.3 regression] ICE with templates and exceptions

["jboyden at geosci dot usyd dot edu dot au" <gcc-bugzilla at gcc dot gnu dot org>]

+ On a SuSE Linux 9.0 system (GCC version: 3.3.1 (SuSE Linux)), the following
code causes an ICE: Segmentation fault:

$ cat ice.cc 
template< typename T >
struct S1
{
    struct S2 {  };

    S1()
    {
        throw S2();
    }
};

template< typename U >
S1< U > f()
{
    try
    {
        S1< U > s;
        return s;
    }
    catch (typename S1< U >::S2 e)  // If 'e' is a reference, the ICE goes away.
    {

    }
}

int main()
{
    S1< int > si = f< int >();
    return 0;
}
