I wasn't able to reproduce the problem on my GNU/Linux.

Perhaps this is a locale issue, could you try
        LC_ALL=C gawk '{gsub(/[\x00-\x1f\x7e-\xff]/,"*");print}' x.x
?

Another question: does the following end with the same error?
        gawk '/[\x00-\x1f\x7e-\xff]/' x.x

And what about this
        gawk '{gsub("[\x00-\x1f\x7e-\xff]","*");print}' x.x
(quotes instead of slashes)?

Arnold has just released gawk 3.1.5, and it's already available on cygwin
site; could you please try this?

I'm just guessing here, but perhaps your answers to the above questions
will help Arnold to identify the problem.

A lot has happened since 1997, when 3.0.3 was released.
In particular, the regex engine was replaced by a totally new code.

HTH,
