Subject: [PATCH] Fixed bug: barriers cannot be active during sweep
|
||||
|
||||
Barriers cannot be active during sweep, even in generational mode.
|
||||
(Although gen. mode is not incremental, it can hit a barrier when
|
||||
deleting a thread and closing its upvalues.) The colors of objects are
|
||||
being changed during sweep and, therefore, cannot be trusted.
