Hello Igor, Your fix for mdev-5468 is the oldest fix in 5.3 that is not merged to 5.5. I've tried merging it. The changes in the code auto-merged, but after that the testsuite failed with crashes. Could you please merge mdev-5468 from 5.3 to 5.5? BR Sergei -- Sergei Petrunia, Software Developer MariaDB | Skype: sergefp | Blog: http://s.petrunia.net/blog
