Subject: Re: [Caml-list] Re: GenerateFold
I figured it out. The following introduction of order and order_type  
[2] triggers the error I was seeing previously [1]. This should be  
enough to reproduce the issue and, hopefully, provide clues on how to  
fix it. I have no clues, btw.

	Thanks, Joel

[2] Code with order and order_type.

type id = string

and program = statement list

and ty =
     [
     | `TyAny
     ]

and statement =
     [
     | `Skip
     | `InputDecls of input_decl list

and subscript = expr list

and input_decl =
     [
     | `InputDecl of id * ty * expr
     | `FunArgDecl of id * ty * subscript
     ]

and expr =
     [
     | `Int of int
     | `Float of float
     | `Str of string
     ]

and order = {
   order_type: order_type;
}

and order_type =
     [
     | `Buy
     | `Sell
     | `Short
