This is a gmcs bug.

It compiles the follow method:
public static int Test<T> (T t) where T : class
{
    return t != default (T) ? 0 : 1;
}

As:

method public static  hidebysig default int32 Test<class T> (!!T t)  cil
managed 
{
    .maxstack 8
    IL_0000:  ldarg.0 
    IL_0001:  brfalse IL_000c

    IL_0006:  ldc.i4.0 
    IL_0007:  br IL_000d

    IL_000c:  ldc.i4.1 
    IL_000d:  ret 
}

You cannot use brtrue/false with an unboxed generic type. gmcs must emit a box
before it.
