BigInteger e = new BigInteger(10);
BigInteger m = new BigInteger(32);
Console.WriteLine(e.ModPow(e, m));

+Fixed in SVN (both HEAD and MONO-1-0).

+The bug was caused by a small error. It wasn't detected because non
+cryptographic test cases are almost inexistant in BigInteger right now
+- and crypto tests deal mostly with odd numbers. BigInteger
+definitively needs more unit tests.
