[odb-users] segmentation fault on linux while operating Mysql database

[Sebastian Cartier]

Hi Boris
I have the same problem as Gao Dejian on *Thu Aug 18 04:44:19 EDT 2016. I
use odb 2.4.0 on g++-5 on a Ubuntu Linux (I tried 2 systems). I checked the
connection with 'show processlist;' in mariadb and it actually establishes
the connection. The stacktrace is as follows:*









*Program received signal SIGSEGV, Segmentation fault.0x000055555555dfda in
odb::mysql::statement_cache::find_object<person> (this=0x0) at
/usr/include/odb/mysql/statement-cache.txx:2424      if (version_seq_ !=
conn_.database ().schema_version_sequence ())(gdb) bt#0  0x000055555555dfda

*It looks like the statement_cache is never initialized. Do you have any
advice for me?*

*Thank you!*
