Hi,

We see that python3 based lttng is continuously crashing on debian-12.
Kernel Version is 6.1.0. Is there some special handling that has to be taken care for debian-12?

Following is the core decode.
Program terminated with signal SIGABRT, Aborted.

Hi Lakshmi,

I'd like to encourage once again to review the bug reporting guidelines 
at https://lttng.org/community/ and include all the necessary 
information including steps to reproduce the issue. Thank you.

To the best of my knowledge there are no special cases for Debian 12 in 
upstream lttng-ust. The Debian source package carries two minor patches 
from what I can see, neither of which seem directly related to the 
python agent.

Could you install the relevant "-dbgsym" packages for libc and 
liblttng-ust or fetch the debug symbols from debuginfod so that the 
addresses are resolved into meaningful symbols?
