[MDEV-5434] ConnectSE: ODBC: "mtr --embedded connect.odbc_postgresql" crashes in longjump Created: 2013-12-11  Updated: 2013-12-16  Resolved: 2013-12-16

Status: Closed
Project: MariaDB Server

 Description   

Note, to avoid this failure in BuildBot, odbc_postgresql is currently
skipped when run with --embedded.

Remove this line from storage/connect/mysql-test/t/odbc_postgresql.test:
--source include/not_embedded.inc

and run "./mtr --embedded connect.odbc_postgresql".
It will crash.

Running "./mtr --valgrind --embedded connect.odbc_postgresql"
gives some idea of might be wrong:

CURRENT_TEST: connect.odbc_postgresql

The unhanded long jumps were caused by memory exhaustion.
Two things have been done:
1 - Handling the long jumps during that process
2 - Reducing the needed memory
