[okular] [Bug 275203] okular crashes when reading some *.chm files

--- 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.

Maybe this bug related to difference in SSE2 implementation in intel and AMD.
The same problem was investigated and solved for game Mass Effect for example:

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.
