IDE: Fire
Version: 10.0.0.2617
Target: Android/iOS/OSX/Net
Description:

Updating old project. Project is a cross-platform library for a product with MacOS / iOS / Android / Windows clients. Project will not build due to apparent compiler bug.

Expected Behaviour:

Code compiles or we get a useful reason why not

Actual Behaviour:

Nasty stack overflow in the “Simplifying Code” phase. Begins like this:
