Strange error in Rational multiplication

[vadimtsushko]

It is probably some rare edge case - I use dart-rational for calculation in biggish dataset and got this first time: I can reproduce this with dart-rational 0.2.0 and Dart VM version: 2.0.0-dev.42.0 (Unknown timestamp) on "linux_x64"

import 'package:rational/rational.dart';

main() {

  var r1 = new Rational(new BigInt.from(4403993), new BigInt.from(1000));
  var r2 = new Rational(new BigInt.from(1384700050), new BigInt.from(9498883));
  var r3 = r1 * r2; /// this line is breaking
  print(r3);

}

This snippet breaks with error

Thanks for the report. Looks like a VM issue. I just created dart-lang/sdk#32739.

Thank you, I'll try to downgrade to 2.0.0-dev.28.0 meanwhile
