I just ran into this issue. I'm trying to write code like this:


where buffer is a bytearray. When bufferLen is greater than 2GB I fail foul of this code in _ctypes.c

    long length;
    length = PyLong_AsLongAndOverflow(length_attr, &overflow);
    if (overflow) {
                        "The '_length_' attribute is too large");
        goto error;

Surely this should not be forcing long on us. Can't it use PyLong_AsSsize_t or perhaps PyLong_AsLongLongAndOverflow?
