Equality comparison with nullables throws at delegate-invoke #67
Description
The following expressions compile successfully, but exceptions are thrown during execution of the resulting delegates. The first is the one i'd actually like to use, and the second is a failed attempt to circumvent the first.
class Foo {
public int? Prop { get; set; }
}
static void Main(string[] args) {
int int32Comparand = 1;
Expression<Func<Foo, bool>> a = foo => foo.Prop == int32Comparand;
var ac = a.CompileFast();
var ar1 = ac(new Foo { Prop = null }); // throws NullReferenceException
var ar2 = ac(new Foo { Prop = 1 }); // throws NullReferenceException
Expression<Func<Foo, bool>> b = foo => Nullable.Equals(foo.Prop, null);
var bc = b.CompileFast();
var br1 = bc(new Foo { Prop = null }); // throws AccessViolationException
}
