Hello Sasan,

you can try to execute sumo under the control of gdb from the shell

gdb -ex run --args <path to your sumo> <your arguments to sumo>

Eventually the gdb will stop and you can request with bt a back-trace.

If you can build sumo on your own, you can try to build a debug version (see https://sumo.dlr.de/docs/Developer/Debugging.html#debug_build) and run gdb on that version.

Regards, Harald

 Is the crash reproducible on other machines?
Can you package a minimal set of input files for reproducing the crash?

    Hello Sasan,

    I've just moved from 1.14 to 1.16 under ubuntu 20.04 (into a
    docker container) and things seem OK for several hours of
    simulation using TRACI PYTHON and also using LIBSUMO, for both
    console and gui. I do not think I've changed something in my
    PYTHON app code when upgrading. Strange it breaks in both cases
    for you.

        Dear all,
        I tried to install SUMO 1.16 on my Ubuntu (both 20.04 and 22)
        by using
        the stable release via apt and comping from the source. In all
        cases,
        I am getting a segmentation fault after some simulation
        seconds. I am
        running sumo without gui, from inside a conda env or just in the
        terminal. I am not sure what is causing the error, but I have
        the same
        setup but running SUMO 1.15 and it is working just fine. Does
        anyone
        have any tips?

        Thanks,
        Sasan
