Error reading metadata

[gusty]

Possible related to this similar issue

Here's a small reproduction:

. Create a new library project
. Paste this code:

namespace Library1

type Class1() =
  static member inline ($) (r:'R, _) = fun (x:'T) -> ((^R) : (static member method2: ^T -> ^R) x)
  static member inline method1 x = Unchecked.defaultof<'r> $ Class1()

. Compile, then reference the dll

#r @"Library1.dll" ;;

unknown(1,1): warning FS3186: An error occurred while reading the F# metadata node at position 3 in table 'ivals' of assembly 'Library1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The node had no matching declaration. Please report this warning. You may need to recompile the F# assembly you are using.

This was working fine before, in all F# versions, even in a beta (or may be it was a pre-release) version of F# 4.0 I tested some months ago was working fine, but now it doesn't and I have a project that is throwing many warnings like this when used from another project. Still they work fine but apart from the warnings the compile time increased, probably related to this.

FWIW this commit into F# 4.0 changed a debug-mode assertion into a warning e5cdef9#diff-c357695ff5c54532cf4bebc7af8ac2aa

The warning can be safely ignored for now but the extra information you've given will help us fix the underlying problem.
