    contrib/flex: Guard against int overflow in sko_push().
    
    sko_sz is an int; doubling it unchecked could overflow and produce a
    huge size_t for realloc(). Bail out if it would overflow.
    
    It's sad that the upstream project hasn't had a new release since 2017,
    so we decided to directly patch the contributed source.
    
    Bug: #3426
