Hi, Otto,

Thank you; I have done that at
https://jira.mariadb.org/browse/CONC-487

However, given the developer's response on
https://jira.mariadb.org/browse/CONC-289 I don't know if they will accept
the patch.

Well, the patch simply sets pointers to NULL after the memory that they
point to has been freed.  They already do that in one other place
(the memset call in mysql_close sets mysql->options.extension to NULL)
with a comment "/* Clear pointers for better safety */" so I hope that
they (and Debian) will accept the patch.

Regards,

Dianne.
