Description c4205691 2016-06-16 02:13:01 UTC
The following:

Imports System
Imports System.Collections.Generic

Public Class Test
    Public Shared Sub Main()
        Dim good As New List(Of String)
        Dim god As Integer = AscW(good(0)(0))
    End Sub
End Class

Causes:

Unhandled Exception:
System.InvalidProgramException: Invalid IL code in Test:Main (): IL_0015: call      0x0a000003

[ERROR] FATAL UNHANDLED EXCEPTION: System.InvalidProgramException: Invalid IL code in Test:Main (): IL_0015: call      0x0a000003

This was observed on:
Visual Basic.Net Compiler version 0.0.0.5943 (Mono 4.0.1 - tarball)
And possibly others (not sure if it still fails on latest though)
