I have already looked at Rene's SVN and the patch and there doesn't
seem to be any relevant change in the above mentioned part of the
code.

Well, if the size were sizeof(SANE_Word), it would be ok. But it isn't.

Just use an editor on backend/avision.c, find this line:

   s->opt[OPT_NUM_OPTS].size = sizeof(SANE_TYPE_INT);

And change it to that one:

   s->opt[OPT_NUM_OPTS].size = sizeof (SANE_Word);

Bye,
