Crashes in Mouse KCM init *** Bug 395121 has been marked as a duplicate of this bug. *** *** Bug 395482 has been marked as a duplicate of this bug. *** *** Bug 395539 has been marked as a duplicate of this bug. *** All duplicates from openSUSE. (In reply to Christoph Feck from comment #5) > All duplicates from openSUSE. Likely a red herring because of different compiler or environment options for additional hardening. This looks like wrong use of KConfig to me, it creates a dangling pointer: https://cgit.kde.org/plasma-desktop.git/tree/kcms/mouse/backends/x11/x11_backend.cpp#n126 Yep. Never crashes here but a minimal test of the same code does produce a valgrind warning. Writing the correct version which keeps the lifespan of the KConfig object does nto produce the warning. Will fix this. I reported my duplicate 395539 less than 24 hours ago. Great to see that you're on top of it. Thanks a lot, keep it up! Git commit ead2c3e859dcb8531df99e87c0fe6eff64650952 by David Edmundson. Committed on 19/06/2018 at 08:02. Pushed by davidedmundson into branch 'Plasma/5.13'. Ref KConfig whilst we're using it Summary: In current code we would have a KConfigGroup with a dangling KConfig deleted after the RHS for the group fetch has finished. Test Plan: Wrote minimal test case of code It produced a valgrind warning (weirdly didn't crash though) Modified to correct version No longer any warnings Reviewers: #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D13599 M +3 -1 kcms/mouse/backends/x11/x11_backend.cpp https://commits.kde.org/plasma-desktop/ead2c3e859dcb8531df99e87c0fe6eff64650952 *** Bug 395613 has been marked as a duplicate of this bug. *** Created attachment 113521 [details]

Could anyone understanding the Plasma fix propose a fix for Akregator? *** Bug 395913 has been marked as a duplicate of this bug. *** Okular is also affected, see bug 395765. (In reply to Christoph Feck from comment #16) > Okular is also affected, see bug 395765. The backtraces are basically identical, seems to be caused by KMainWindow. I don't see anything wrong with a first glance though. *** Bug 395691 has been marked as a duplicate of this bug. *** |
