~~Actually, it looks like maybe its from a debug print left in.~~

Let me see if I can track it down...

EDIT: It is from this commit: github.com/LinuxCNC/linuxcnc/commit/5d05...80a914ca8d6881a8e4a1

Prior to that commit I get no "error" on shutdown in the terminal, after that, I get the following:

Code:

<__main__.QTVCP object at 0x7fa9064912e8>
Shutting down and cleaning up LinuxCNC...
task: 523 cycles, min=0.000001, max=0.020910, avg=0.010125, 0 latency excursions (> 10x expected cycle time of 0.010000s)
Note: Using POSIX non-realtime
LinuxCNC terminated with an error.  You can find more information in the log:
    /home/plasma/linuxcnc_debug.txt
and
    /home/plasma/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal

Running Buster 10 (MX Linux 19.4)

Moved the thread to qtvcp so Chris would see it

I'm stumped on how to fix this.
There isn't really an error (well in this case I'm assuming it's the usual segfault).
It is known problem with pyqt, that seems to be in this case sensitive to exiting HAL (which is the part I added back)

I'm open to ideas from coding experts.

Thanks for the help, hopefully I can fix that

I'm a bit confused since normally the segfault "errors" show up on versions greater than Buster.

Both paulsao and I are running Buster, which seemed to be previously immune from this (I thought anyways).

Otherwise, I am out of ideas, it's probably way above my pay grade.

Maybe this wasn't above my pay grade after all...

Made some headway, Chris pushed this fix: github.com/LinuxCNC/linuxcnc/commit/4683...968022550a6395c38ff4

Should be improved, but report back if it isnt!
