You do not need to reproduce if you still have the core files and installed the debug symbols for your version, just run again gdb on the core and get the backtraces.

Hi Andrew,
the 5.2.4 does not contain the 5.3-pre1 workaround yet.
So if you test the workaround you need to install the lastest 5.3 from the git master debian repository.
But nevertheless it would be good to look at the backtrace, while you have it.
Cheers,
Henning

Hi Andrew,
Download from here: http://deb.kamailio.org/kamailio52/pool/main/k/kamailio/
You have kamailio-dbg v5.2.4 (latest 5.2) for all distros...
Example for amd64+stretch: http://deb.kamailio.org/kamailio52/pool/main/k/kamailio/kamailio-dbg_5.2.4%2Bstretch_amd64.deb

strange - it should be there, as it is available on deb.kamailio.org.

As part of our release process, I don't think we can release master branch of Kamailio.

Hello,
did you get core files? If yes, it would be good to see the gdb bracktraces.
Have you used the pre-loaded library workaround?
The code was not backported to branch 5.2 yet, I wanted to wait a bit and see if there are reports with good/bad results. If you want to use it, then you have to install nightly builds from master branch (development version, should be 5.3.0-pre1 at this moment).

Hi Daniel,
Thanks a lot for this work; it's definitely important that Kamailio
build against OpenSSL v1.1, and I'll be happy to contribute some testing
in a live environment in the coming weeks. Much appreciated.
