But it sounds like all the debugging information is already available
in the issue pointed out by Glenn?  Emacs gets a signal that causes it
to background.  The problem is why the signal is delivered, and its
cause is outside Emacs, could be the WSL itself, could be ncurses when
it runs on WSL, could be something else.  But definitely not Emacs.
