First bug: in function rrd_fetch_fn_libdbi() variable 'struct sql_table_helper table_help'
field 'filename' is uninitialized. So, if a sql error happens, it does not print an error like this
rrd_set_error( "libdbi: problems connecting to db with connect string %s - error: %s",th->filename,dbi_errstr);
instead of, it dumps core.

Second bug: when the output data buffer is allocated, it allocated for 'rows-1' max index, but in
'fetch loop' 'idx' may be equal to 'rows', so it needs one more extra record in data.
