Application: plasmashell (6.4.4) ApplicationNotResponding [ANR]: false Qt Version: 6.9.1 Frameworks Version: 6.17.0 Operating System: Linux 6.15.9-201.fc42.x86_64 x86_64 Windowing System: Wayland Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)" DrKonqi: 6.4.4 [CoredumpBackend] -- Information about the crash: This hung it and the shell, for < 2 s. Immediately, the shell closed, then reinvoked, as if I'd executed `kquitapp6 plasmashell && plasmashell`. About the warnings at the start of the trace, I've asked https://stackoverflow.com/questions/73812207/gdb-core-dump-warning-cant-open-file-memfdmagicringbuffer-deleted-during-f/73814664#comment140676093_73814664:~:text=If%20you%20think%20you%20can%20file%20such%20a%20bug%2C%20that%20would%20be%20of%20use.%20I%20encounter%20this%20every%20time%20I%20attempt%20to%20debug%20a%20crash%2C%20but%20have%20very%20little%20idea%20of%20any%20of%20the%20concepts%20explained%20here.%20I%20have%20at%20least%20located%20sourceware.org/bugzilla/show_bug.cgi?id=29969. That was all I was able to locate on the topic, so I've been unable to remediate them. Even if I had been able to, this reproduces so rarely/inconsistently that I doubt that I would have been able to generate a new one. The crash can be reproduced sometimes. -- Backtrace (Reduced): #5 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at pthread_kill.c:44 #6 0x00007f4fe6282163 in __pthread_kill_internal (threadid=<optimized out>, signo=6) at pthread_kill.c:89 #7 0x00007f4fe6228a7e in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #8 0x00007f4fe62106d0 in __GI_abort () at abort.c:77 #9 0x00007f4fe62116f3 in __libc_message_impl (fmt=fmt@entry=0x7f4fe63c244c "%s\n") at ../sysdeps/posix/libc_fatal.c:134 #10 0x00007f4fe628c1f5 in malloc_printerr (str=str@entry=0x7f4fe63c53b0 "malloc_consolidate(): unaligned fastbin chunk detected") at malloc.c:5829 #11 0x00007f4fe628cecc in malloc_consolidate (av=av@entry=0x7f4fe63f6ac0 <main_arena>) at malloc.c:4903 #12 0x00007f4fe628f930 in _int_malloc (av=0x7f4fe63f6ac0 <main_arena>, bytes=4096) at malloc.c:4099 #13 0x00007f4fe6290dee in __GI___libc_malloc (bytes=4096) at malloc.c:3414 #14 0x00007f4fe6a41f09 in allocateData (allocSize=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/tools/qarraydata.cpp:139 #15 allocateHelper (objectSize=1, alignment=16, capacity=4078, option=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/tools/qarraydata.cpp:181 #16 allocateHelper (objectSize=1, alignment=16, capacity=<optimized out>, option=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/tools/qarraydata.cpp:157 #17 QArrayData::allocate1 (dptr=dptr@entry=0x7fff77fe1890, capacity=<optimized out>, option=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/tools/qarraydata.cpp:211 #18 0x00007f4fe69cf7e8 in QTypedArrayData<char>::allocate (capacity=<optimized out>, option=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/tools/qarraydata.h:129 #19 QArrayDataPointer<char>::QArrayDataPointer (this=0x7fff77fe1890, alloc=<optimized out>, n=<optimized out>, option=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/tools/qarraydatapointer.h:58 #20 QByteArray::reallocData (this=0x7fff77fe1a40, alloc=<optimized out>, option=<optimized out>) at /usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/text/qbytearray.cpp:1984 Reported using DrKonqi

(In reply to Roke Julian Lockhart Beedell from comment #0) In retrospect, this might be a duplicate of https://bugs.kde.org/show_bug.cgi?id=506642#c10. I'll tentatively mark it as so; apologies if not or so. [^1] I should have checked https://bugzilla.redhat.com/show_bug.cgi?id=2376516#c12 first.
