The address of the static field cannot be used at this point
f#compiler

Hi,

I get the above compiler error when accessing a static let value in a static member property.

When I copy the static let value to a local value inside the static property first, it compiles, but fails at runtime with "the static initialization of a type resulted in static data being accessed recursively before it was fully initialized."

What is causing this? There is no recursive dependency as far as I can see - the static let value is just a constant DateTime.

Thanks, Kurt

.

Could you post the code? This works for me:

1
2
3

type T() =
  static let x = System.DateTime(1,2,3)
  static member X = x

Yes, sorry I wasn't entirely clear - the crucial bit is you need to take the address of x. Say by calling a method on it:

1
2
3
4
5
6
7
8

type T() =

  static let x = System.DateTime(1,2,3)

  static member X = 

    x.AddDays (float 2)

If X is a method, same error (I removed that bit from my OP, sorry)

You're right - this looks like a bug to me. Oddly, it only seems to affect static let-bound instances of value types. I sent a message to fsbugs.

However, the workaround you proposed in your original post does seem to work for me:

1
2
3
4
5

type T() =
  static let x = System.DateTime(1,2,3)
  static member X =
    let x = x
    x.AddDays (float 2)

OK, keep me informed of the outcome please.

The actual case I am seeing the exception is more involved, as you might imagine, but I haven't been able to cut it down.
