I'm writing some perlxs code that goes something like this: 
void
add_entry(hash)
        HV * hash
    PREINIT:
        SV * key;
        SV * val;
    CODE:
        key = newSViv( (IV)someint );
        val = newSViv( (IV)otherint );
        hv_store_ent( hash, key, val, 0 );

[download]
This leaks memory. However, if I make the key be a char * and instead use hv_store it does not leak memory. So here's my question: Do I have to free up the SV* key when I'm done using it in hv_store_ent, or is some other error causing my memory leak?
