+Summary: long * -int gives bad results (big positive integer)
+
+Description of Problem:
+Multiplying a long with a negative integer results in a big positive
+integer. There are no (visible) overflow involved.
+
+
+Steps to reproduce the problem:
+1. Compile the following source
+
+using System;
+class T {
+	static void Main () {
+		int seconds = -59;
+		Console.Out.WriteLine ("{0} * {1} == {2}", TimeSpan.TicksPerSecond,
+seconds, (TimeSpan.TicksPerSecond * seconds));
+	}
+}
+
+2. Execute
+
+
+Actual Results (Mono):
+
+10000000 * -59 == 42949672370000000
+
+
+Expected Results:
+
+10000000 * -59 == -590000000
+
+
+How often does this happen? 
+Always
+
+
+Additional Information:
+The same binary gives the right result when executed by the MS runtime.
