<p><a href="https://github.com/linuxmaniac" class="user-mention">@linuxmaniac</a> - that is not solving it, setting ptr to NULL is effective only inside the curl_shm_free().</p>
<p>To me it looks like some pointers that are given to a CURL function, which is going to free them at some point, are also freed inside http_async_client module. Not that familiar with the code, but I think some of the <code>shm_free(</code>) inside <code>set_query_params()</code> should not be done. I guess that the fix is in the direction of: when a field from <code>struct query_params</code> is given to a CURL function, it should be set to <code>NULL</code> so <code>set_query_params()</code> doesn't free it again. Now, identifying when the field is given to a CURL function requires to look deeper a the code of the module, not being familiar with, I couldn't do it quickly and no much spare time here at this moment.</p>
