BUG#13556441: CHECK AND REPAIR TABLE SHOULD BE MORE ROBUST [4]
Problem description: mysql server crashes when we run repair table on currupted table. Analysis: The problem with this bug seem to be key_reflength out of bounds (186 according to debugger). We read this value from meta-data segment of .MYI file while doing mi_open(). If you look into _mi_kpointer() you can see that the upper limit for key_reflength is 7. Solution: In mi_open() there is a line like: if (share->base.keystart > 65535 || share->base.rec_reflength > 8) we should verify key_reflength here as well.
