oqgraph v3 should resolve this.
obviously has to be tested on "all" platforms before that can be validated as
fact,

Title:
OQGraph tests crash on MariaDB 5.3.1 Beta
Status in Maria:
New
Status in OQGraph Engine for MariaDB:
In Progress
Bug description:
Running the tests on a Gentoo x86_64 box for MariaDB 5.3.1.
I noticed that the oqgraph.basic and oqgraph.binlog tests crashed.
They both fail on INSERT with the same backtrace.
Logs:
oqgraph.binlog [ fail ]
Test ended at 2011-09-22 10:04:01
CURRENT_TEST: oqgraph.binlog
mysqltest: At line 21: query 'insert into graph(origid, destid) values (1,3),
(3,1)' failed: 2013: Lost connection to MySQL server during query
The result from queries just before the failure was:
drop table if exists graph;
CREATE TABLE graph (
latch SMALLINT UNSIGNED NULL,
origid BIGINT UNSIGNED NULL,
destid BIGINT UNSIGNED NULL,
weight DOUBLE NULL,
seq BIGINT UNSIGNED NULL,
linkid BIGINT UNSIGNED NULL,
KEY (latch, origid, destid) USING HASH,
KEY (latch, destid, origid) USING HASH
) ENGINE=OQGRAPH;
SET binlog_format = row;
insert into graph(origid, destid) values (1,3), (3,1);
Server [mysqld.1 - pid: 13481, winpid: 13481, exit: 256] failed during test

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.
key_buffer_size=0
read_buffer_size=131072
max_used_connections=1
max_threads=153
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 60714 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
