Prerequisites

Steps to reproduce

# !! BROKEN: 
#   * `default(IntPtr)` (or `default`) are converted to System.Int32(!) 0  on compilation (the same happens in regular .NET SDK probject)
#   * C# code can call such a method just fine, but PowerShell complains.
#  * Workaround: use `new IntPtr()` as the default value.
(Add-Type -PassThru -Name Foo1 -MemberDefinition @'
    public static void Bar(IntPtr p = default(IntPtr)) { }
'@)::Bar()

Expected behavior

The method calls should succeed (it produces no output).

Actual behavior

The method call fails with the error below.
