On Linux Debian 11, eiskaltdcpp-qt/stable,now 2.4.2-1 amd64

systemd-coredump[1247224]: Process 1244184 (eiskaltdcpp-qt) of user 1000 dumped core.

.zst file linked above, any dea what to try? Should i:

$ cd program_folder
$ gdb program_name
run
once crash:
bt

? anyone able to understand crashdumps?

I have updated some system apps recently, maybe it can be the cause too and i need to restart.

Do you use eiskaltdcpp packages from official Debian repos? Please show output:

dpkg -l | grep eiskaltdcpp

$ gdb program_name

Yes, backtrace is necessary for debugging. But you need to install dbgsym packages for eiskaltdcpp first. And then:

gdb eiskaltdcpp-qt
$ run
... crashed ...
$ bt full

And show backtrace here.

[slrslr]

I think yes, Debian main repo:

$ apt info eiskaltdcpp-qt|grep Sources

APT-Sources: http:https://deb.debian.org/debian bullseye/main amd64 Packages

$ dpkg -l | grep eiskaltdcpp

ii eiskaltdcpp-common 2.4.2-1 all common files for EiskaltDC++
ii eiskaltdcpp-qt 2.4.2-1 amd64 EiskaltDC++ GUI based on Qt
ii eiskaltdcpp-qt-data 2.4.2-1 all data files for EiskaltDC++ Qt
ii libeiskaltdcpp2.4 2.4.2-1 amd64 core library for EiskaltDC++

If coredump mentioned earlier not enough, how to install dbgsym packages for eiskaltdcpp on Linux Debian please? Computer reboot not helped btw.

Even LinuxDC++ began crashing after like 48 hours.
Mentioned eisklatdc ran via CLI end with:

Error: No word lists can be found for the language "cs".

i have found that when i switch networkinterface to non existing one on line:
wg0
in ~/.config/eiskaltdc++/DCPlusPlus.xml
Then app does not crash. Crash happens when i switch back to wg0, restart app and always a few seconds after start when file uploads are initiated.

"eiskaltdcpp-qt-2.2.10-710-x86_64.AppImage" also crash..
Creash is prevented when i disable networking or set config (as shown above) to use non existing network interface..
ideas please?
@tehnick how to install dbgsym packages for eiskaltdcpp on Linux Debian please?

In the meantime i am using AirDC WebUI https://airdcpp-web.github.io/docs/installation/linux-binaries.html
