AFAIK the regexp and font-lock code are identical in both versions (of course the Lisp is, but both modules are highly dependent on C support so there's a possibility of difference.) Are you building with Mule? Er, scratch that, just send the usual bug report for both platforms. Thanks! Also, try nuking the progress meter, which is a substantially different implementation and known to be very buggy on X11.
