+Summary: crash when running a pure managed console assembly compiled with MS.NET 1.1
+
+Description of Problem:     
+While running a proprietary program that I can't give out, I get the     
+segfault below. It is reproducible across 1.1.10 and 1.1.13.2 on x86 and     
+current SVN on amd64.     
+     
+     
+Steps to reproduce the problem:     
+1. run the program with specific options with or without --debug or under    
+gdb or not, very reproducible.    
+    
+Sometimes the stack is so trashed that gdb can't make heads or tails of    
+it, though.    
+     
+Actual Results:     
+Program received signal SIGSEGV, Segmentation fault.

+    
+     
+     
+Expected Results:     
+  Other runs of the same program work fine, not sure what the problem   
+is..   
+     
+How often does this happen?      
+Every time.     
+     
+Additional Information:     
+I can coordinate with people on IRC for further debugging, but can't  
+provide access to the program in question. It is scarily reproducible 
+across different machines, distros, and mono versions.
