Description jqt4 2019-02-20 15:57:23 MSK
Исследую с помощью gdb завершение программы с Segmentation fault.
После подачи команды bt падает сам gdb:
gdb apt-indicator
...
Thread 1 "apt-indicator" received signal SIGSEGV, Segmentation fault.                                                                                                                       │
