           Summary: [Regression] Locking doesn't work properly
           Product: Mono: Runtime
           Version: SVN
          Platform: x86
        OS/Version: Other
            Status: NEW
          Severity: Blocker
          Priority: P5 - None
         Component: misc
        AssignedTo: mono-bugs at ximian.com
        ReportedBy: juraj at hotfeet.ch
         QAContact: mono-bugs at ximian.com
          Found By: ---


Test case:
==========
using System;

class Test {
  static object some_lock = new Object();

  static void Main(string[] args) {
    lock(some_lock) {
      lock(some_lock) {
        Console.WriteLine("This should never be reached!!!");
      }
    }
  }
}

Output:
=======
This should never be reached!!!


The test case should deadlock, without any output.
This has been broken probably for some time now. Otherwise commit r85090*
(results in nested lock for the same object) would have led to other problems
surfacing...
