           Summary: gmcs requires ()/[] in 'new' when not needed.
    Classification: Mono
           Product: Mono: Compilers
           Version: SVN
          Platform: x86-64
        OS/Version: openSUSE 11.1
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: jpryor at novell.com

gmcs (mono-trunk) in r132609 always wants () or [] in a 'new' expression even
if it isn't needed -- for example, with collection initializers.


  // collection initializers...
  using System;
  using System.Collections.Generic;

  class Test {
    public static void Main ()
      new List<string> { Foo(1), Foo(2) };

    static string Foo (int n)
      return n.ToString ();

With r132609:
ci.cs(8,42): error CS1526: A new expression requires () or [] after type
ci.cs(8,42): error CS8032: Internal compiler error during parsing, Run with -v
for details

With Mono 2.0 (openSUSE 11.1), or Mono 2.4, or .NET 3.5 CSC, this code compiles
without error.

To workaround, within mcs/mcs, run
$ svn up -r132591 .
