Moin moin I cannot reproduce this locally. * What version of konsole are you using exactly? * What's the shell you're using? * Anything special configured in konsole? (i.e. have you tried the default profile) mfg Tobias (In reply to Tobias C. Berner from comment #1) 12.2-RELEASE-p10 FreeBSD Version 21.08.2 /bin/sh nothing fancy in my profile, happens with default, brand new, and existing profile. tried rebooting and rebuilding konsole, no change. only kde related hacks are qmake fixes to allow qt-3d to build correctly for < haswell arch. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248155 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255753 for completeness sake: also running openmpi --without-ofi https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256037 and py-scipy WITH_ATLAS https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257400 Can't reproduce it either -- this **could** be a 12-specific thing, or because konsole has one million options, any one of them. Please attach a screenshot of your konsole before the crash, and one of the during-the-crash state (it complains about the shell not exiting?) What environment are you running this in? The backtrace looks valid. The code around the backtrace doesn't look silly either -- but it should not be complaining about a running process, anyway. Created attachment 228604 [details]
konsole end file kernel running.jpg
konsole looks normal so I didn't make a picture, infact during some upgrades last night I found that tabs will close fine via Ctrl-D, its only the final tab. only difference to error message state is "~:sh:- Konsole" is the window title. not sure what you mean by environment, but I'll post another text file with lldb events commented, and what the stdout during a crash to the command line from another window launching konsole, and env output scrubbed/modified to eliminate personal information, session cookies, etc. I'll reply back with the contents of the text file, but it might get mangled in the comment, which is why i'm doing both.

(In reply to Adriaan de Groot from comment #3) I've been holding off a 13 upgrade as I was hoping some patches would make it in to the tree so I could re-build my system, but I might just go forward with the patches I need in a custom ports tree local branch and give it a go. I have no sentimental attachment to 12.2, just no time to take the system down for the rebuilds, and some long overdue backups prior to them. If yall are under 13 and have no issues, works for me to try that as its the plan anyway to get there. But if it is a 12.2 issue, and its resolvable, that would be cool too. It looks like there is a nullptr being held potentially for the konsole window itself, so maybe it is attaching tracking to process 0, theoretically the kernel? This is beyond my level of understanding, or if process 0 would even be considered the kernel. If you can give me some guidance on how to pull out that nullptr using lldb to see what the structure is just give me an idea of how to find it as to my Make.conf outside of setting westmere I have no CFLAGS nor CXXFLAGS set, CPUTYPE?=westmere ###### CFLAGS+= -march=${CPUTYPE} -mtune=${CPUTYPE} ###### CXXFLAGS+= ${CFLAGS} COPTFLAGS+= -O -pipe obviously I have plenty of tweaks in my ports.conf portconf config, but nothing crazy, and not much for kde, mainly media related, software synths, Atlas BLAS, nvidia related, and such, none of which should affect konsole. As indicated only kde hack is the qmake changes to make qt5-3d build non-AVX to let things like pyside2 build and qgis. a few others to get openmpi and py-scipy as referenced above by pr's text output of attached clean output file.

Then changing them back to 1, triggers the problem and crash. (In reply to Adriaan de Groot from comment #8) Only under 12.2 or even with 13? I have 1's for all those, presumably the default setting. (In reply to Adriaan de Groot from comment #8) furthermore I can confirm security.bsd.see_other_uids=0 allows konsole to behave properly on my machine. no error with Ctrl-D returning it to security.bsd.see_other_uids=1 shows the errors again.

konsole no longer allows a close file, exit nor ctrl-D, from shell without claiming there is a running process. if you click cancel instead of ignore konsole crashes. the running process is indicated to be "kernel" . all KDE components upgraded to new versions from console shell, not under X11. output from KDE crash handler Executable module set to "/usr/local/bin/konsole".
