In this way, Uglify will call the AST_Binary.print methods recursively and can lead to stack overflow error.
You can try to replace doit() function call with it's actual code to reduce call frame.

// ./lib/output.js
AST_Node.DEFMETHOD("print", function(stream, force_parens) {
        var self = this;
        stream.push_node(self);
        if (force_parens || self.needs_parens(stream)) {
            stream.with_parens(doit);
        } else {
            // doit()
            stream.prepend_comments(self);
            self.add_source_map(stream);
            self._codegen(stream);
            stream.append_comments(self);
        }
        stream.pop_node();

        function doit() {
            stream.prepend_comments(self);
            self.add_source_map(stream);
            self._codegen(stream);
            stream.append_comments(self);
        }
    });
