When I get a model with NSPredicate, the results count is more than zero. But I cannot get the item with [results objectAtIndex:0]. It crashed and told me container overflow detected. Is this issue occurred to anybody ? Need help.

Realm Objective-C only supports being built with Address Sanitizer enabled when its core database library is also built with Address Sanitizer enabled. Since we don't have publicly-available builds of the core database library with ASan support, you'll need to avoid building Realm Objective-C with ASan enabled for now.
