Fair enough. What's the official behavior of malloc_zone_register supposed to be? If it's supposed to not handle multiple- registrations, then I can post a documentation bug to better document that that's the behavior and that furthermore it needn't be called after malloc_create_zone. If it's supposed to handle multiple- registrations (i.e., politely does nothing), then there's clearly a bug either in it or somewhere in the Safari-used code that is revealed by it, and that needs to be radared.

malloc_create_zone calls malloc_zone_register itself. That comment is a bit confusing, and I'm not sure under what circumstances anyone would want to call malloc_zone_register themselves. I'm also not sure why this leads to a spinlock, but clearly something doesn't like having the same zone in the zone list twice.

Please file a different bug: "malloc_zone_register(0 of an already registered zone should result in an error". -- Terry _______________________________________________ Do not post admin requests to the list.
