При попытке отладки приложений, использующих OpenGL из Mesa, gdb два раза выкидывает в shell. Воспроизведение (на примере приложения glmark2): 1. apt-get install glmark2 glmark2-debuginfo 2. gdb $(which glmark2) 3. run Результат: Дважды выкидывает из gdb обратно в shell. С помощью команды fg можно вернуться в gdb. Ожидаемое поведение: В shell выкидывать не должно. glxinfo: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 400 (Braswell) OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.3.4 OpenGL core profile shading language version string: 4.50 Лог запуска glmark2: $ gdb $(which glmark2) GNU gdb (GDB) 8.2.50.20180917-alt2 (ALT Sisyphus) Copyright (C) 2018 Free Software Foundation, Inc.
