+
+
+
+Expected Results:
+
+No crash!
+
+How often does this happen? 
+
+Every time I try, on two different machines.
+
+Additional Information:
+
+I also reported this problem to the F# development team, as I cannot judge who is responsible. 
+Apparently the executable fscp10.exe works fine under .NET.
