I am using the QScintilla wheels and I think, they are not built with
debugging. Will this work nevertheless? I have used gdb in ages and
don't know any more, how to do that.

Attach gdb to the process before you crash it. You might have to allow
ptrace, "echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope"
The "gdb --pid <PID>" and inside the gdb shell "continue" and after the
crash "bt"
Having debug symbols would be better, but even w/o it will at least
give a general idea about the nature of the segfault.
Does that btw. mean that you're using the same version of QScintilla,
just on different OS stacks?
That is correct. When I switch Ubuntu to use X11, the crash does not
happen. Therefore I think, it is related to Wayland or the combination
of Qt6 and Wayland.
