Possible to have two stubs active at the same time?

[Jamie Lyon]

Hi,

 

Is it possible to have two 'axis2_stub_t's active at any one time? When
I try to free the objects I get the stack trace included at the end of
the message.

 

This is upon freeing the second axis2_stub. If I delete the first before
creating the second it works perfectly fine, it's only if they're both
created at the same time.

 

I should also note that this only appears to happen if both stubs have
sent a message, if either one has only been created, and not actually
used, both can be freed without any incident.

 

The general steps are as follows:
1) Create axutil_env_t

2) Create neethi_policy

3) Create stub 1 from axutil_env_t and neethi_policy

4) Create a second neethi_policy

5) Create stub 2 from axutil_env_t and second neethi_policy (also tried
with a second, separate axutil_env_t, to no avail)

6) Send a message from stub 1

7) Send a message from stub 2

8) Free stub 1

9) Free stub 2 (crash)

 

If you cannot reproduce this, I will try and write a test case.

 

Is this a known problem?

 

Thanks,

Jamie
