Comment:
I don't know why exactly, but I cannot create a core dump file.
```
% ls -l telegram-desktop 
-rwxrwxrwx 1 piotr piotr 66749648 Jul 20 21:06 telegram-desktop
% pwd
/tmp
% ulimit -c unlimited
% ./telegram-desktop

I am not very experienced with this, but from reading `man 5 core` I understand that there might be many reasons for why the core dump is not being created.
