Summary: nonatimic Properties behave wrong Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: libobjc AssignedTo: unassig...@gcc.gnu.org ReportedBy: js-...@webkeks.org It seems nonatomic properties retain and autorelease the result, which is breaking existing code targeting the Apple runtime. This bug has been also in the GNUstep runtime and the Cocotron runtime, it seems this bug has been copied to the new GNU runtime now. The Apple doc says: "If you specify nonatomic, then a synthesized accessor for an object property simply returns the value directly." <http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ObjectiveC/Articles/ocProperties.html> I have written a property implementation which is known to be compatible to the Apple runtime which is quite short and I'd like to contribute. It is currently licensed under the QPL, but I plan to relicense it as GPL if you are interested. If you need a testcase, there is a test for properties included in ObjFW <https://webkeks.org/hg/objfw>, in src/PropertiesTests.m, which also fails. It works well with the Apple runtime and the included properties implementation in src/objc-properties.m - this is also the implementation I'd like to contribute. Let me know if you are interested.
