|Description:||I am using func_odbc to connect to a sybase database via tds.|
Occasionally this causes Asterisk to crash but I am not able to recreate it. The same sql query used in func_odbc will not cause a re-crash.
****** ADDITIONAL INFORMATION ******
I am using func_odbc in a non-standard way in that I pass a whole query to the function from the dialplan rather than just a variable.
This is the entry in func_odbc.conf

Please specify the version of unixODBC, the driver you're using to connect to Sybase and its version.

I am using UnixODBC 2.2.12 and freetds 0.64.
The Sybase database is ASA 7.0.4

In gdb, with this core, I need to see the output of:
FYI, this would appear to be a bug in unixODBC, but I would like to be sure, before I send you upstream to them.

I have uploaded the requested output.

Okay, I'm satisfied that this is a bug in unixODBC. Please report this issue to their development team.

Can you give me an idea of how Asterisk is causing this bug in unixODBC, i.e. if there is something I can avoid to stop crashing Asterisk.
Also, as this bug is causing Asterisk to crash, shouldn't Asterisk be able to handle this case and not crash?

I don't know the answer to any of those questions, other than to say that if a library segfaults the process, it will take Asterisk down. This could also be a bug in FreeTDS, for that matter, but the code which is segfaulting is clearly UnixODBC, not FreeTDS.

Closing, as the issue is in the interaction between UnixODBC and FreeTDS, not fixable within Asterisk.
