-- Information about the crash:
plasmashell consistently crashes for me if I click the WiFi icon in Task Manager and then disconnect from the currently-connected network in plasma-nm.

Please note that I'm using a development version of GCC, and as such, if the crash looks ridiculous, please let me know and I'll run with it on that side.

The crash can be reproduced every time.

Comment 2 Sam James 2024-12-02 22:03:21 UTC 
nicofee and I discussed it briefly on IRC, apparently there's some other reports in sentry at least. What I don't yet get is why it's specific to plasma-nm given nothing in the bt looks related. I'm hoping to find a reproducer that doesn't involve killing all my network connections.

The fact it involves coroutines again is suspicious - see bug 494693. So it's possible that I need to try extract some testcase to report to GCC (the issues mentioned in bug 494693 were investigated & fixed).

That seems plausible. See https://bugs.kde.org/show_bug.cgi?id=499100 which is also suspected to be a GCC bug

The original backtrace doesn't seem to be related to coroutines though
Comment 7 Marco Martin 2025-02-04 13:39:21 UTC 
the crash with:

#14 0x00007f06840696d1 in Kirigami::Platform::PlatformTheme::emitSignalsForChanges (this=<optimized out>, changes=<optimized out>) at /usr/src/debug/kde-frameworks/kirigami-6.8.0/kirigami-6.8.0/src/platform/platformtheme.cpp:905
#15 0x00007f0684069c2b in Kirigami::Platform::PlatformThemeChangeTracker::~PlatformThemeChangeTracker

seems also akin to something else i seen in sentry which is about things emitting signals when they are destroyed, there was a (fixed) issue about that in ksvg, but i guess also in Kirigami::PlatformTheme
Comment 8 Sam James 2025-02-04 14:21:43 UTC 
Two updates:
1) Some fixes were committed last night in GCC for a bunch of coroutine issues. I'm going to try those out.
2) Jakub's suggested workaround of -fno-range-for-ext-temps seems to have helped too.
Comment 9 Sam James 2025-02-15 16:41:18 UTC 
I came first ;)

But other bug is fixed, so marking as dupe of that.
