--- Comment #2 from Adrian Wielgosik <adrian.wielgosik at gmail dot com> ---
Your operator< doesn't seem to satisfy strict weak ordering. Once I rewrote it
to a basic but safer version:

bool operator< (const chave& lhs, const chave& rhs) {
    if(lhs.numeros_ord != rhs.numeros_ord)
        return lhs.numeros_ord < rhs.numeros_ord;
    return lhs.estrelas_ord < rhs.estrelas_ord;
}

It seems to work fine to me.

(Also, when testing with clang/GCC, try using AddressSanitizer or valgrind,
you'll have a better chance of catching illegal memory accesses.)
