[okular] [Bug 275203] okular crashes when reading some *.chm files
https://bugs.kde.org/show_bug.cgi?id=275203 --- Comment #26 from Mihail Kasadjikov --- Hi. Now I still use the old KDE4, okular, chm backend and so on (debian jessie). But Xserver, mesa and gcc are fresh. And now okular works without crashes. $ dpkg -l okular* libchm1 *mesa* xserver* libgcc1 libstdc++6 | awk '/^ii/{print $2" "$3}' | column -t glx-alternative-mesa0.8.0+nmu1 libchm1 2:0.40a-3+b1 libegl-mesa0:amd64 20.3.0-1 libegl-mesa0:i386 20.3.0-1 libegl1-mesa:amd64 20.3.0-1 libegl1-mesa:i386 20.3.0-1 libgcc1:amd64 1:9.3.0-11ubuntu0~14.04 libgcc1:i3861:9.3.0-11ubuntu0~14.04 libgl1-mesa-dri:amd64 20.3.0-1 libgl1-mesa-dri:i38620.3.0-1 libgl1-mesa-glx:amd64 20.3.0-1 libgl1-mesa-glx:i38620.3.0-1 libglapi-mesa:amd64 20.3.0-1 libglapi-mesa:i386 20.3.0-1 libgles2-mesa:amd64 20.3.0-1 libgles2-mesa:i386 20.3.0-1 libglu1-mesa:amd64 9.0.0-2 libglu1-mesa:i386 9.0.0-2 libglx-mesa0:amd64 20.3.0-1 libglx-mesa0:i386 20.3.0-1 libosmesa6:amd6420.3.0-1 libosmesa6:i386 20.3.0-1 libstdc++6:amd649.3.0-11ubuntu0~14.04 libstdc++6:i386 9.3.0-11ubuntu0~14.04 libwayland-egl1-mesa:amd64 20.3.0-1 mesa-common-dev:amd64 20.3.0-1 mesa-utils 8.2.0-1 mesa-va-drivers:amd64 20.3.0-1 mesa-va-drivers:i38620.3.0-1 mesa-vdpau-drivers:amd6420.3.0-1 mesa-vulkan-drivers:amd64 20.3.0-1 mesa-vulkan-drivers:i38620.3.0-1 okular 4:16.08.2-1.1 okular-extra-backends 4:16.08.2-1.1 xserver-common 2:1.20.9-2.1 xserver-xephyr 2:1.20.9-2.1 xserver-xorg1:7.7+16.1 xserver-xorg-core 2:1.20.9-2.1 xserver-xorg-core-dbgsym2:1.20.9-2.1 xserver-xorg-input-evdev1:2.10.4-1.1 xserver-xorg-input-kbd 1:1.9.0-1.1 xserver-xorg-input-mouse1:1.9.2-1.1 xserver-xorg-legacy 2:1.20.9-2.1 xserver-xorg-video-amdgpu 19.1.0-2.1 xserver-xorg-video-radeon 1:7.10.0-1 Maybe this bug related to difference in SSE2 implementation in intel and AMD.

https://bugs.kde.org/show_bug.cgi?id=275203 Mihail Kasadjikov changed: What|Removed |Added Component|CHM backend |XPS backend --- Comment #21 from Mihail Kasadjikov --- Guys. All information that I can collect as a user I've provided in 2012. And no any recomendations about how and where to dig, no another activity at all was for 6 years. I use KDE 4 and Debian 8 on my workstation and laptop and even backported (rebuilt) the most fresh KDE4 related packages from debian-testing into my local repo some years ago. But I am not a c++ developer and can not do deep investigation into source code or libs, stack traces and so on. What can i do as an user except "just throw out KDE4"? -- You are receiving this mail because: You are watching all bug changes.

On my old laptop with intel i7-620L it works with both documents normally. Maybe the cause is in SSE4a or AVX support? -- You are receiving this mail because: You are watching all bug changes.
