The error is thrown from the analyze function in Expr.js in Saxon-JS 1.2.0:

            if (loops++ > 1000) {
                throw XError("looping???", "SXJS0004");
            }

This analyze function is called from analyze-string and tokenize in CoreFn.js, and formatNumberSeq in Numberer.js.

Note that the error still exists in Saxon-JS 2.0 code, but has been slightly updated. The relevant analyze function in now found in Push.js:

            if (loops++ > input.length * 10) {
                throw new XError("analyze-string looping???", "SXJS0004");
            }

I see the error thrown running the demo with Saxon-JS 1.2.0, but not with Saxon-JS 2.0; I guess because of the loops++ > condition change.

Copied 2.0 change for loops++ > condition to Saxon-JS 1 branch, and committed. (The error message is just left as is, because the error shouldn't ever actually happen...)
