Could this and Bug 499081 be caused by compiler issues? IIRC Fedora was having issues with GCC 15; see Bug 499100. Apparently it's a GCC 15 bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116506 *** Bug 499469 has been marked as a duplicate of this bug. *** (In reply to Nate Graham from comment #4) > Apparently it's a GCC 15 bug: > https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116506 It's plausible, looking at https://crash-reports.kde.org/organizations/kde/issues/122628 all reports come from Fedora Rawhide with that GCC version We do have some slightly different but still very similar crashes involving other distros though: https://crash-reports.kde.org/organizations/kde/issues/122339 https://crash-reports.kde.org/organizations/kde/issues/100399 https://crash-reports.kde.org/organizations/kde/issues/108886 so I wouldn't tell for sure. https://invent.kde.org/plasma/plasma-nm/-/merge_requests/409 sounds like it should fix this *** Bug 496961 has been marked as a duplicate of this bug. *** Fedora applied a workaround for the GCC bug, that should fix it https://src.fedoraproject.org/rpms/plasma-nm/c/91545a88f47b496a14d6f1fdee37b2564f6a0a37?branch=rawhide |
