[Vala] trying to allocate 4294967295 bytes

[Sebastian Spaeth <sebastian sspaeth de>]

I have created this evas.vapi function:

        [CCode (array_length = false)]
        [NoArrayLength]
        public weak uchar[] data_get( bool for_writing );

(it is supposed to return a void* pointer which is still owned by the class)
which translates into:

        data = (_tmp4_ = (_tmp3_ = evas_object_image_data_get
(self->priv->barchart, TRUE), (_tmp3_ == NULL) ? ((gpointer) _tmp3_) :
_vala_array_dup2 (_tmp3_, -1)), data_length1 = -1, data_size =
data_length1, _tmp4_);

which fails as:

GLib-ERROR **: /build/buildd/glib2.0-2.20.1/glib/gmem.c:136: failed to
allocate 4294967295 bytes
aborting...

Any clues as to what I am doing wrong?

The C function definition is:
void *evas_object_image_data_get(const Evas_Object *obj, Eina_Bool
for_writing)
