Summary:  ilrun throws exception when parsing hex values

Original Submission:  When parsing a numeric string in hexadecimal form (using 
NumberStyles.AllowHexSpecifer), Int32.Parse() on .NET treats values greater 
than 0x7fffffff as negative numbers. For example, 0xf0000000 turns in the 
decimal value -268435456, instead of throwing an exception. On the other hand, 
ilrun throws an exception. From reading the docs, throwing an exception seems 
like the correct behavior, but this is not consistent with the behavior under 
Rotor. I will double-checked on .NET as soon as I find someone to run it for me.

The attached program prints -268435456 on Rotor but throws an exception on 
ilrun:

Uncaught exception: System.OverflowException: Valid Int32 values are between 
-2147483648 and 2147483647, inclusive
        at System.Private.NumberParser.ParseInt32(String, NumberStyles, 
NumberFormatInfo, Int32) in ./System/Private/NumberParser.cs:605
        at System.Int32.Parse(String, NumberStyles, IFormatProvider) in 
./System/Int32.cs:78
        at System.Int32.Parse(String, NumberStyles) in ./System/Int32.cs:91
        at Testing.Main()
