System.Exception: Error interpreting stacktypes for IL_0006:

I were trying to port BigInteger to Cosmos the .NET version is too complex and will need to plug 99% of .NET so I've found this implementation that is really more simple: http://www.codeproject.com/Articles/2728/C-BigInteger-Class
SingleImpl.cs is now using BigInteger as the range of float overcome that of ulong but now the code does not compile anymore this is the error:
6:44:13.265590 Msg: Detecting fields for type 'Cosmos.Debug.Common.Method' 06:44:13.281600 Msg: Error: Exception: System.Exception: Error compiling method 'SystemBooleanSystemSingleEqualsSystemObject': System.Exception: Error interpreting stacktypes for IL_0006: Brtrue ---> System.Exception: Invalid type in PopTypes!

I suppose it is something done in BigInteger.cs as removing the variable declaration it compiles again.

The "simplified" BigInteger ad not the methods Equals with the other parameter as BigInteger... the branch that actually failed was this one: if (mantissa == 0) where 'mantissa' was a BigInteger. Adding that method the problem gone away but after I started to get Stack Overflow!
