Here's the code:

1049                 tdsdump_log(TDS_DBG_INFO1, "tds_put_data: null
param\n");
1050                 switch (curcol->column_varint_size) {
1051                 case 4:
1052                         tds_put_int(tds, -1);
1053                         break;
1054                 case 2:
1055                         tds_put_smallint(tds, -1);
1056                         break;
1057                 default:
1058                         assert(curcol->column_varint_size);
1059                         /* FIXME not good for
SYBLONGBINARY/SYBLONGCHAR
1059 (still not supported) */
1060                         tds_put_byte(tds, 0);
1061                         break;
1062                 }

It seems you're using a NULL parameter for a column with a weird
datatype, and we don't determine the size correctly.  :-/

Use a different datatype, I think.
