Mono discards field initializers when the ctor has dynamic arguments.

With "D:\Applications\Mono-2.11.4\bin" and
"C:\Windows\Microsoft.NET\Framework\v4.0.30319" in the path on my Windows 7

===== CtorDynamic.cs =====
class Test {
    Test(int i) { fld2 = 10; }
    Test(char c) { fld2 = 23; }
    static Test foo(dynamic d)
        return new Test(d) { fld = 23454 };
    public static void Main(string [] args)
        int i = 0;
        Test t = foo(i);
        System.Console.WriteLine("Test, fld = "
                                 + t.fld + ", fld2 = " + t.fld2);
    int fld;
    int fld2;
===== end =====

$ csc CtorDynamic.cs
Microsoft (R) Visual C# Compiler version 4.0.30319.17929
for Microsoft (R) .NET Framework 4.5

$ ./CtorDynamic.exe
Test, fld = 23454, fld2 = 10

$ mcs CtorDynamic.cs

$ ./CtorDynamic.exe
Test, fld = 0, fld2 = 10

Note the difference in output.
