Description
We had a MariaDB 5.2.10 server that was continuously crashing:

Initially we thought this would be caused by hardware issues, but it's a repair of an archive table that triggers this. I've uploaded the table causing this crash to the FTP server.

Re: Archive table corruption crashing MariaDB signal 11
Re: Archive table corruption crashing MariaDB signal 11
Hi,
You are saying that it's crashing on 5.2.10. Do you have a server where this table works okay?
From what I see, any action on this table also causes crashes on MySQL-5.1.60, MySQL-5.6.4, MariaDB-5.2.8.
When did the crashes start? On which server version was this table updated for the last time?

Hi,
> You are saying that it's crashing on 5.2.10. Do you have a server where this table works okay?
No, it seems to fail everywhere (fortunately the data inside the table is not important to us though).
> When did the crashes start? On which server version was this table updated for the last time?
The crash started after an unclean shutdown of the machine. It was last updated in 5.2.10.
Re: Archive table corruption crashing MariaDB signal 11
So, as said before, any action on the provided table causes a server crash. Apparently, the table got corrupted due to the unclean shutdown as Dreas mentioned in his comment, but hopefully there is still a way to avoid a crash and report a table corruption instead.
Re: Archive table corruption crashing MariaDB signal 11
This is reoccurring on one of our servers. Including backtrace output:
