Error: Cannot infer key and value ... about fable-react-native

Looks like some JavaScriptCore bug led to this behavior. I didn't find any info about it, but this.tag in the following snippet was set to undefined right inside the constructor in certain situations:

  setType("Fable.Helpers.ReactNative.Props.TransformsStyle", TransformsStyle);
  const FlexStyle = __exports.FlexStyle = class FlexStyle {
    constructor(tag, data) {
      this.tag = tag | 0;
      this.data = data;
    }
    ...

After replacing original JSC with this one I didn't receive this error anymore.

Hmm, strange. I'd like to test this with Fable 2 to see if it's still happening...
