Mono FSharpC error with Type Provider

I have this code in Yoghurt.Fruit.fs

module Yoghurt.Fruit
 open FSharp.Data
 type Fruit = JsonProvider<"fruit.json">
 let fruit = Fruit.Load("fruit.json")
 let fruitExists name = fruit.Callouts |> Array.exists (fun el -> el.Name = name)

I am running this compile command in OSX with Mono fsharpc --nologo -r ../../fsharp-lib/Fhsarp.Data/FSharp.Data.dll Yoghurt.Fruit.fs -a -o:bin/Yoghurt.Fruit.dll

I get this error

* Assertion at threads.c:1360, condition 'internal' not met

Illegal instruction: 4

(nb first ' before internal is actually ` edited here for formatting)

I have no idea what this error means and why I am getting it. I have a collection of .fs files that I am compiling in this way (to run tests against them - and then finally use them all in a .fsx file). In the main .fsx file I have this code 

#r "/Users/philharvey/Documents/code/fsharp/fsharp-lib/Fhsarp.Data/FSharp.Data.dll"
open FSharp.Data
type Fruit = JsonProvider<"fruit.json">
let fruit = Fruit.Load("fruit.json")
let fruitExists name = fruit.Callouts |> Array.exists (fun el -> el.Name = name)

and this works just fine. I would really like to pull out this code into a module to be separately tested (there is other functionality besides fruitExists that I haven't listed because I have boiled my problem down to this).

Anyone have any insight?

fsharpc gives F# Compiler for F# 3.0 (Open Source Edition)

(and for extra info I am using this for tests Mono.framework/Versions/3.0.10/bin/nunit-console4

FSharp.Data Version 1.1.5

Edit 3

More information: I have just tested an .fsx through fsharpi and fsharpc using the JsonProvider as above. It works through fsharpi but not fsharpc (gives the same error above). I have also done a test with fsharpc using the template (basic) from here http://blogs.msdn.com/b/fsharpteam/archive/2011/07/30/f-console-application-template.aspx. Gives the same error when the type provider is used.

Solution

  • I have just upgraded to mono 3.2.1 and made sure I am on latest version of F# 1.1.9 and the problem has gone away.
