           Summary: On invalid base constructor call: Internal compiler
                    error during parsing.
    Classification: Mono
           Product: Mono: Compilers
           Version: 2.4.x
          Platform: x86-64
        OS/Version: Ubuntu
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#

This code is invalid (an artifact of my C++ habits):

   using C = System.Collections.Generic;

   class List<T> : C.List<T>
      public List(int Size) : C.List(Size) {}

The base constructor call "C.List(Size)" should actually be "base(Size)".

But instead of getting a regular error message from the compiler, I got this:

$ csc -v Test.cs
System.InvalidCastException: Cannot cast from source type to destination type.
  at Mono.CSharp.CSharpParser.yyparse (yyInput yyLex) [0x00000] 
  at Mono.CSharp.CSharpParser.parse () [0x00000] 
Test.cs(5,33): error CS8032: Internal compiler error during parsing, Run with
-v for details
Compilation failed: 1 error(s), 0 warnings

Reproducible: Always
