+Summary: Segmentation fault in runtime - test case attached
+
+Description of Problem:
+I encountered this bug in a program that has been developped using Visual 
+C# Express, and that runs fine on windows platform. When I tried it on a 
+Linux machine using mono it crashed, so I tried to narrow down the problem 
+and ended up with this small test case. It has been tested with today's 
+SVN version, and version 1.1.13.2
+
+Steps to reproduce the problem:
+1. Get the attached test.cs file
+2. Compile it using "gmcs test.cs"
+3. Run with "mono test.exe"
+4. In the test case, there are three comments (1, 2, 3).
+   If any of those lines are commented out, the program runs fine...
+
+Actual Results:
+=================================================================
+Got a SIGSEGV while executing native code. This usually indicates
+a fatal error in the mono runtime or one of the native libraries
+used by your application.
+=================================================================
