minecraft-launcher: segfault in versions later than 0.9.66 #4961

There are some GL-related error messages, and the backtrace also seems to be in a 3d-related library (while creating a window?). But maybe some related 3d-library is in a different path in Gentoo. |

You know what? This thing has 24 cores idling and I've been meaning to put git-bisect to use for some time now. [a few minutes later] Guess I'll have a look at ea564eb, I'll let you know if I find out anything. |

Turns out, it's specifically that video group handling. Only now did I notice the I'm not too familiar with the internals, so maybe you can shed some light on the purpose of novideo.? |

Thanks for debugging and for specifying that the problem happens on nvidia. The aforementioned bisected commit from #4632 would be my first guess as well. So as I suspected in #4632, it seems that the proprietary nvidia driver indeed I think I'll change the checks to keep the video group to also consider the To clarify the environment: Are you using openrc and the proprietary nvidia driver? Are you using udev/eudev? Which seat manager are you using if any? Examples: logind, elogind, seatd |
Correct. rc_controller_cgroups="YES"
rc_cgroup_mode="unified"
rc_cgroup_controllers="cpuset cpu io memory hugetlb pids systemd"
rc_cgroup_cleanup="YES"
rc_crashed_start=YES
rc_depend_strict="YES"
rc_parallel="NO"
rc_shell=/sbin/sulogin
rc_sys=""
rc_tty_number=12
unicode="YES"
udev, yes.
None, plain old startx on tty2 (at which point agetty chowns the tty device to my user for the duration of my session AFAIK). |
Description
Hard SIGSEGV when running minecraft-launcher in corresponding profile.
Steps to Reproduce
firejail "--private=${custom_path?}" minecraft-launcher(LC_ALL=C.utf8 is my default)Click to expand
Seems to be a solid NULL-deref.
Expected behavior
It's supposed to launch the game as usual.
Actual behavior
The above error is thrown and no game ever appears.
Behavior without a profile
Doesn't start at all
Additional context
The problem was introduced after firejail-0.9.66.
That version works as expected, while the update to 0.9.68 introduces the error.
firejail version 0.9.66 (working)
firejail version 0.9.68 (broken)

Output of
LC_ALL=C firejail /path/to/programThe above output is pretty much the same with the older version too, only after that output the start button is triggered at which point the segfault occurs, but there is no more output from that point onwards.
Output of
