MySQL Verification Team
Hi Mr. do, Thank you for your bug report. I have analysed your stacktraces and concluded that you are using a debug build. So, why are you using a debug build and not a binary package from our site. You can download it from dev.mysql.com. Next, we can not do anything without a repeatable test case. Hence, if you get a crash from a production binary every time you OPTIMIZE that table, then we need full contents of that table in the form of the mysqldump output. Thanks in advance.

(gdb) p new_col->mtype $2 = 4 (gdb) p col->mtype $3 = 12 How to repeat: There is no case to reproduce the issue currently. It is a occasionally produced issue, maybe because of the concurrent between OPTIMIZE TABLE and ALTER TABLE (alter column type in the statement). Suggested fix: Is the debug assert necessary here? or there is something wrong while we do the concurrency control between table rebuild and table alter?
