Bug ID: 418552
Summary: Random crashes on ppc64
Product: kate
Version: 19.12.0
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: peterjpiwowar...@gmail.com
Target Milestone: ---
Application: kate (19.12.0)
Qt Version: 5.12.5
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-3-powerpc64 ppc64
Distribution: Debian GNU/Linux bullseye/sid
-- Information about the crash:
I've seen occasional random crashes while editing C sources on Debian/ppc64
sid. In the specific case this backtrace was generated from, I had all files
matching drivers/macintosh/windfarm*.? in the Linux source tree open. I can't
say for sure what input triggers it, or whether it even triggers on a user
input (as opposed to randomly whenever the window is open), but a quick glance
over the backtrace suggests it probably is some mouse/keyboard event. More
information (possibly) coming as I continue to see crashes, but I don't have
constant access to this machine or use it very regularly.
The crash can be reproduced sometimes.
-- Backtrace:
