As root in tty3 I attached GDB to kwin_wayland and as soon I got back
to
the graphical session, the system got stuck and I could not neither
return back to tty3, so I had to use Magic SysRq key to restart the
system.
The wiki says to try to use SSH, but it would be useless too since I
am
not able to use the graphical session if kwin_wayland is attached to
GDB
Of course you need to continue once you attached gdb. I'm not sure
what you want to achieve but debugging the running display manager on
the same system - well it's even more impossible than debugging the
running window manager on X11. I'm working with nested kwin_wayland
running in gdb to do debugging.

A running from bash Plasma, when it crashes[1], sends a message like
The Wayland connection broke. Did the Wayland compositor die?
so I was trying to figure out if kwin_wayland crashes too
[1]: https://bugs.kde.org/show_bug.cgi?id=378707
I think you are looking at a false positive here. Given the backtrace I
think the message is a side effect not the cause. If the Wayland server
had problems everything would die not just Plasma. And it would not
crash - at least not directly. It could only crash in the cleanup
handler and that's not the case here.
