Package: firejail Version: 0.9.44.8-1~bpo8+1 Severity: normal Dear Maintainer,
when passing --allow-debuggers to firejail to enable strace or gdb to work inside firejail (in order to figure out why the sandboxed application doesn't work), firejail crashes immediately on start-up: sascha.silbe@twin:~$ firejail --allow-debuggers echo ok Reading profile /etc/firejail/default.profile Reading profile /etc/firejail/disable-common.inc Reading profile /etc/firejail/disable-programs.inc Reading profile /etc/firejail/disable-passwdmgr.inc ** Note: you can use --noprofile to disable default.profile ** Parent pid 8465, child pid 8466 *** Error in `firejail': free(): invalid pointer: 0x000055b39282d354 *** Error: cannot establish communication with the parent, exiting... sascha.silbe@twin:~$ -- System Information: Debian Release: 8.8 APT prefers stable APT policy: (990, 'stable'), (500, 'stable-updates'), (100, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-0.bpo.2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages firejail depends on: ii libapparmor1 2.9.0-3 ii libc6 2.19-18+deb8u9 Versions of packages firejail recommends: ii iptables 1.4.21-2+b1 ii xauth 1:1.0.9-1 ii xpra 0.14.10+dfsg-1 ii xserver-xephyr 2:1.16.4-1 firejail suggests no packages. -- Configuration Files: /etc/firejail/firejail.config changed: xephyr-screen 1280x720 -- no debconf information
