Changing service client options after between messages
------------------------------------------------------
Key: AXIS2C-1355
URL: https://issues.apache.org/jira/browse/AXIS2C-1355
Project: Axis2-C
Issue Type: Bug
Components: core/clientapi
Affects Versions: 1.6.0
Environment: Axis2/C from svn (26 Feb 2009)
Linux 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386

Priority: Minor
I want to use a single service client to send multiple messages, with different
options (i.e. SOAP action). Basicly I do the following.
1. Create service client object.
2. Create options object and set options.
3. Set options to service client (axis2_svc_client_set_options).
4. Execute message (axis2_svc_client_send_receive).
5. Create new options object and set new options.
6. Set new options to service client (axis2_svc_client_set_options).
7. Execute new message (axis2_svc_client_send_receive).
When doing step 7, I get the following message when running under Valgrind.

My guess is that the op_client tries to access the old options object from step
2/3. This is no longer valid as it has been freed when setting the new options
(step 6).
Or is svc_client not designed to send multiple messages with different options?
