<h3>Description</h3>
<p>I'm using a few serial http_async_client functions in my config, I found one setup in which kamailio stops with a segmentation fault just doing one call. I can reproduce it in my concrete config, but can't put my finger on the bleeding. I do have a core file.</p>
<h3>Troubleshooting</h3>
<h4>Reproduction</h4>
