pua_json module not compatible with library libjson-c-dev 0.15.2

[henningw]

There seems to be an incompatibility in the pua_json module related to the libjson-c-dev" version.
The module crashes after start on the first actions on version 0.15.2 (e.g. from Debian bullseye).

It works with version 0.12 (e.g. Debian buster).

What version of kamailio are you running? I run 5.5.2 on bullseye with no issues.
Just trying to reproduce this

[henningw]

Thanks for the reply. The version in question was Kamailio 5.6.3.

[henningw]

Just let me know if you need more information

@eschmidbauer anything I could do? Did you managed to have a look to it maybe? Thank you.

[eschmidbauer]

Hi @henningw can you give me more details on how to reproduce the crash?
e.g. install from source, packages.
I would be happy to take a look and fix it if I can reproduce the issue locally

[henningw]

Thanks for the fast reply. We observed some time ago on an environment, but right now I don't have the means to reproduce it, unfortunately. I just looked into the report from the time, and it was easy to reproduce by just installing e.g. 5.6.3 from github and using the libjson-c-dev version 0.15.2. The version 0.12 worked. 5.6.3 is of course also now a bit older.

[eschmidbauer]

ok, i will compile 5.6.3 on bullseye and test it out!
give me some time to work on it
