It actually does matter, and the interface does check for alignment. The reason is that V8 relies on those pointers being aligned: it uses this fact as part of the mechanism for deciding to ignore them. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
