Sorry, I forgot to say it but yes I verified that the pv module is loaded. Actually I added traces in the mod_init function of the http_async_client_module and when I remove my faulty line I can see the full init taking place including the pv_api being filled. When I put back my faulty line, the traces I added are not displayed the seg fault occuring before the init. -- You are receiving this because you are subscribed to this thread.

Unless there is still an issue despite the fix, I'm going to close this issue. @miconda, I'm planning to backport it to 4.4 branch too, but this patch will now make kamailio fail to start if the **http_async_client** module is loaded before **pv**. This is the way it always have been documented, but until now it worked no matter what the loading order was. Is it ok to backport it anyway? -- You are receiving this because you are subscribed to this thread.
