+Summary: Mono does not report NullRef on method calls on Null object
+
+Please fill in this template when reporting a bug, unless you know what you are  
+doing.  
+Description of Problem:  
+Mono does not raise a NullRef. exception where it should. Min handels the error  
+ok. The problem is in SourceAnalyzer.cs . A member object "factory" is initialized  
+but in the constructor there is a local object named factory wich is initialized  
+instead of the member object so the member object is never initialized. Then there  
+is a method call on the member onject wich is null in another member method. Mint  
+raises a NullRef exception but mono does not. Both mono and mint confirms that the  
+object is null through a if( ob == null) test.  
+  
+Steps to reproduce the problem:  
+1. Run linecounter.exe with mono and mint  
+2. look in SourceAnalyzer.cs  
+3.   
+  
+Actual Results:  
+ It looks like execution with success 
+  
+Expected Results:  
+ NullRefernceException in Linecount.SourceAnalyzer::Analyze 
+  
+How often does this happen?   
+ Allways 
+  
+Additional Information:  
+ The source code and binaries are in the supplied tar.gz file
