If you are using the default setup then the -R switch is implemented by
a Lisp function calling itself recursively.  I suppose it could recurse
too deeply if you really have a big directory tree, and hit a limit on
either allowed recursion depth or stack space, the latter of which might
(?) depend on the compiler.  You could try the ELisp debugger.

If you want a work-around then customize ls-lisp to call an external ls
program; the one in Cygwin seems to work fine, and was the benchmark
against which I developed the ls-lisp support.
