+Subject: [PATCH] Don't try to clear cache on garbage objects
+
+Method cache can be cleared during lazy sweeping.  An object that will
+be collected during lazy sweep *should not* have it's method cache
+cleared.  Soon-to-be-collected objects can be in an inconsistent state and
+this can lead to a crash.  This patch just leaves early if the object is
+going to be collected.
+
+Fixes [Bug #17536]
