Description

The following program fails with an internal compiler error:

--------------------------------------------------------------------------------

enum Colors:
ORANGE
BLACK
MAGENTA

class ColorAttribute(System.Attribute):
def constructor(c as Colors):
pass

class Foo:
[Color(Colors.ORANGE)]
public bar as int

--------------------------------------------------------------------------------

The error is as follows:

attrtest.boo(12,10): BCE0055: Internal compiler error: Type must be a type provided by the runtime.
Parameter name: enumType.

Changing the "Colors" type in the attribute constructor to a plain object is a workaround for this problem.

Looks like it is a SRE gotcha. yay!
This works on Mono, and the crash is within SRE CustomAttributeBuilder.

the 'regression' was a typo! "def contructor" instead of "def constructor" huhu, I think we should get some warning about likely typos for constructor/destructor (after all this typo possibility does not exist in say C#)

Fixing c# integration issue caused this issue to reappear in 9f757fb991ff2fd08b4b864300624b5a6a42433d

The workaround for now is to define the enum in a separate assembly from the attribute.
