Testcase

Description of Problem:
gmcs does not give an error on the attached test case while csc does.

Steps to reproduce the problem:
1. Try and compile attached test.cs: gmcs test.cs
2. 


Actual Results:
Successful compile

Expected Results:
test.cs(18,8): error CS0136: A local variable named 'a' cannot be declared in this scope because it would give a different meaning to 'a', which is already used in a 'child' scope to denote something else

How often does this happen? 
Everytime

FYI, I found this bug when trying to compile the debugger on Windows. So, once this is fixed the debugger will have compile errors.

This causes problems building System.dll with csc. I get the following error with CSC that is not present with the mono compiler (r158840).

  System.Security.Cryptography.X509Certificates\X509Certificate2Collection.cs(223,12): error CS0136: A local variable named 'msg' cannot be declared in this scope because it would give a different meaning to 'msg', which is already used in a 'child' scope to denote something else
