2013-09-29T04:59:17 [4418] Query: INSERT IGNORE INTO `table100_memory_int_autoinc` ( `c27` , `c31` , `c58` ) VALUES ( -6532864 , 'q' , 1 )

The INSERT IGNORE may have been the one that caused the issue. Remember also the UPDATE IGNORE we saw in bug 1168265.

Not 56qual, likely shared with 5.5

Is it possible to reduce the testcase?

(sorry if we discussed this on IRC already)
