Sorry, I can't reproduce this here.  There's a slight chance that this
is because my ls.exe is not a Cygwin program, but I doubt that's the
cause.

(Anyway, why do you switch to ls.exe after you already have a Dired
buffer produced by ls-lisp.el?  Does the problem happen if you do the
switch before visiting the directory?)

Did you try starting Emacs under GDB in the first place?
