+Bug#: 40564
+Product: Mono/Runtime
+Version: unspecified
+OS Details: Windows XP Pro
+Status: NEW   
+Priority: Normal
+Component: misc
+AssignedTo: mono-bugs@ximian.com

+TargetMilestone: ---
+Summary: Odd pause and gc.log produced.
+Description of Problem:
+I have a couple of programs that under Microsoft's runtime throw either a 
+NullReferenceException or a SEHException.  It's one or the other, but 
+it's not consistant.  Under mono 0.23 these programs run, however, they 
+pause for say 10-15 seconds with 100% cpu load, then continue running as 
+expected.  A gc.log file is produced with contents like so:
+Needed to allocate blacklisted block at 0xa200000
+Needed to allocate blacklisted block at 0xa270000
+Steps to reproduce the problem:
+1. Run program.
+Actual Results:
+Thrown exceptions as noted above under Microsoft's runtime.  Pause and 
+gc.log produced under Mono 0.23.
+Expected Results:
+No exceptions, pauses, or logs produced.
+How often does this happen? 
+Every execution.
+Additional Information:
+I'm happy to provide assemblies and sources, however, these examples 
+require a library that I've written (the successor to CsGL) which is not 
+publicly available yet, but I'm happy to provide.  They also require 
+OpenGL support as well as GLUT.  If someone would like to contact me, I'd 
+be glad to supply all the needed code and additional notes on what's 
+going on.
