+ * server/as_environment.h,.cpp: Initialize _original_target, as this
+ absence was causing segfaults. Convert the call stack to a static
+ one.
+ * server/swf_function.cpp: Use a class for ensuring the call stack,
+ rather than doing so manually.
+ * server/Property.h,.cpp: Initialize differently.
+ * server/as_value.cpp: Be more careful about return values.
+ * testsuite/actionscript.all/LoadVars.as: Clean up debugging code.
+ * server/namedStrings.h,.cpp: Add 'super' to known strings.
+ * server/vm/ActionExec.cpp: No need to check call stack, as it is
+ guaranteed correct through use of FrameGuard class.
+
2007-11-21 Zou Lunkai <address@hidden>
* server/as_value.cpp: to_number() convert invalid float literal
