** Description changed: + [ Impact ] + + Gnome shell crashes on double free + Problem is occurring if dual monitor is used. Second monitor is repeatingly blank and activated again. At the bottom it probably contains the upper part of the first monitor. I had the same problem at 18.04 when using gdm3 without wayland during logon. - ProblemType: Crash - DistroRelease: Ubuntu 18.10 + [ Test case ] + + - Run gnome-shell with multimonitor + - No flashing should happen on gdm initialization + + Also we should monitor crashes in e.u.c + + [ Regression potential ] + + Low, the proposed fix is part of the current stable branch upstream and + not changed in further revisions. + + -- + + ProblemType: CrashDistroRelease: Ubuntu 18.10 Package: gnome-shell 3.29.90-2ubuntu1 ProcVersionSignature: Ubuntu 4.17.0-9.10-generic 4.17.17 Uname: Linux 4.17.0-9-generic i686 ApportVersion: 2.20.10-0ubuntu9 Architecture: i386 AssertionMessage: double free or corruption (fasttop) CurrentDesktop: ubuntu:GNOME Date: Mon Sep 3 21:02:58 2018 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" ProcCmdline: /usr/bin/gnome-shell ProcEnviron: - LANGUAGE=en_US:en - PATH=(custom, no user) - XDG_RUNTIME_DIR=<set> - LANG=en_US.UTF-8 - SHELL=/bin/bash - Signal: 6 - SourcePackage: gnome-shell + LANGUAGE=en_US:en + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/bin/bash + Signal: 6SourcePackage: gnome-shell StacktraceTop: - __libc_signal_restore_set (set=0xbfcd5e9c) at ../sysdeps/unix/sysv/linux/nptl-signals.h:80 - __GI_raise (sig=6) at ../sysdeps/unix/sysv/linux/raise.c:48 - __GI_abort () at abort.c:79 - __libc_message (action=do_abort, fmt=<optimized out>) at ../sysdeps/posix/libc_fatal.c:181 - malloc_printerr (str=str@entry=0xb6b437e8 "double free or corruption (fasttop)") at malloc.c:5350 + __libc_signal_restore_set (set=0xbfcd5e9c) at ../sysdeps/unix/sysv/linux/nptl-signals.h:80 + __GI_raise (sig=6) at ../sysdeps/unix/sysv/linux/raise.c:48 + __GI_abort () at abort.c:79 + __libc_message (action=do_abort, fmt=<optimized out>) at ../sysdeps/posix/libc_fatal.c:181 + malloc_printerr (str=str@entry=0xb6b437e8 "double free or corruption (fasttop)") at malloc.c:5350 Title: gnome-shell assert failure: double free or corruption (fasttop) UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo
