It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. To report this bug, see http://kb.askmonty.org/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.

@Elena Stepanova，
upload datadir tar.gz file to ftp.askmonty.org/private done.
filename: Issues_MariaDBServer_MDEV-7333.tar.gz
Thank you.
So, it happens if the table was initially created with Tokutek binaries and had ROW_FORMAT in the definition (which MariaDB's version does not have). To reproduce:
On a Tokutek build (I used mariadb-5.5.38-tokudb-7.1.7):
create table t2 (i int) engine=TokuDB row_format=tokudb_lzma;
Then start MariaDB (e.g. current 5.5 tree) on the same datadir:
MariaDB [test]> show create table t2 \G ERROR 2013 (HY000): Lost connection to MySQL server during query

Hi,
Can you upload the whole datadir (importantly, the <datadir>/<schema>/<tablename>.frm file and all <datadir>/toku files) to our ftp.askmonty.org/private?
