[Mono-list] mono vs mint misbehaviour

[Stef Van Dessel]

Hi,

I've been writing a small application in C# lately, and I stumbled
upon something strange. I've "reduced" the fault to this:

using System;

namespace whatever
{
	class Application
	{
		static void Main(string[] args) {
			long temp = 0x00;
			// Console.WriteLine("{0:X}", temp);
			// this fails with mono, not with mint
			for (int i = 0; i < 2; i++) {
		  			temp += ((long) 0x01 << i);
			}
			Console.WriteLine("{0:X}", temp);
		}
	}
}

Output with mint: (good)
[stef@weepee stef]$ mint TestCase3.exe 
3

Output with mono: (bad)
[stef@weepee stef]$ mono TestCase3.exe 
2
RESULT: 0

It looks like the byte shifting is not happening for whatever reason.

The workaround is to replace:
@@ -14 +14,2 @@
-		  			temp += ((long) 0x01 << i);
+					long t = (long) 0x01 << i;
+		  			temp += t;

This works with both the jit and the interpreter.

Both these versions also compile fine with csc - A csc compiled 
executable also misbehaves on mono and not with mint.
