[SR-Users] q_malloc crash on Kamailio 5.2.3 with http_async_query function

[Federico Cabiddu]

Hi,
I've seen the github issue, I'll have a look asap.
To be clear, are you using http_async_query in dialog's event route also in
4.4.x or is this something new in your routing script?

Regards,

Federico
