[Pgpool-general] pgpool-II child process is segfaulting

[Tatsuo Ishii]

Can you try CVS HEAD?

After 3.1 released, I have committed some fixes regarding memory handling.
For your convenience I have attached patches.

> Hallo,
> 
> we have a Java application that is executing a larger sequence of SQL operations including table manipulations and content modifications within one connection. When we are running these operations through pgpool-II, the pgpool child process handling it always dies with a segmentation fault. But it's not always the same SQL Statement that is causing the segfault.
> 
> Our setup is as follows:
> - pgpool-II-3.1 on a Linux-x86_64 server. We also encountered the segmentation fault with pgpool-II-3.0.4 before trying out version 3.1.
> - the pgpool configuration is reduced to a minimum, that is the connection cache, the master slave and the load balance mode are off. The replication mode is enabled but only one backend is defined.
> - PostgreSQL server version is 9.0.4
> - the Java application uses the postgreSQL JDBC driver in version 9.0.801
> 
> Do you have an idea what might be causing this behavior?
> 
> For some additional details I attached a backtrace. I can also provide the debug messages of the child process, if you want to have look at them.
> 
> Thanks in advance.
