This is another example where the input isn't valid FormCalc, so the processing should be halting relatively quickly, instead of producing JS. The FormCalc stack has significant issues with grammar conformance that need to be addressed.

We are closing all ooms and timeouts that are unreproducible. We won't be filing such bugs in future.
