Summary: plasmashell crashed occasionally with
"malloc_consolidate(): unaligned fastbin chunk
detected" when clicking on the Networks icon in the

-- Information about the crash:
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Desktop-Live-Rawhide-20250212.n.0.x86_64.iso on bare metal. Plasma
6.3.0 on Wayland started. I clicked on the Networks icon in the system tray
repeatedly. plasmashell crashed with the error "malloc_consolidate(): unaligned
fastbin chunk detected" when I clicked on the Networks icon one of those times.
The trace was different from other crashes I've reported such as Bug 499927,
Bug 499218, and Bug 499185, and plasmashell crashed with traces like those when
clicking on the Networks icon earlier in the same session. The problem might be
due to a GCC 15 problem with C++ coroutines
https://bugs.kde.org/show_bug.cgi?id=499218#c4
The crash can be reproduced sometimes.
