+Summary: linears optimization bug on x86_64
+
+Description of Problem:
+With the linears optimization enabled (the default) the attached testcase
+fails on x86_64.
+
+
+Steps to reproduce the problem:
+1. Compile testcase
+2. Run testcase
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+
+Expected Results:
+No Exception at all.
+
+How often does this happen? 
+Always.
+
+Additional Information:
+This happens on x86_64 but not on x86 and it happens with the default

+Tested with mono 1.1.8.3 and trunk as of today
+
+This bug makes it impossible to use the bzip2 decompressing routines of
+SharpZipLib.
