---------------------------------
Labels: core (was: )
> objc_msgSend causes EXC_BAD_ACCESS with plugins on arm64
> --------------------------------------------------------
>
> Key: CB-6150
> URL: https://issues.apache.org/jira/browse/CB-6150
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Affects Versions: 3.4.0
> Environment: iOS 7.0.6 arm64
> Reporter: Joris Verbogt
> Labels: core
>
> This bug was mentioned before in https://issues.apache.org/jira/browse/CB-5888
> The code in CDVCommandQueue line 197:
> objc_msgSend(obj, normalSelector, command);
> Causes a EXC_BAD_ACCESS on arm64.
> According to Apple's docs at
> https://developer.apple.com/library/ios/documentation/General/Conceptual/CocoaTouch64BitGuide/ConvertingYourAppto64-Bit/ConvertingYourAppto64-Bit.html
> :
> An exception to the casting rule described above is when you are calling the
> objc_msgSend function or any other similar functions in the Objective-C
> runtime that send messages. Although the prototype for the message functions
> has a variadic form, the method function that is called by the Objective-C
> runtime does not share the same prototype. The Objective-C runtime directly
> dispatches to the function that implements the method, so the calling
> conventions are mismatched, as described previously. Therefore you must cast
> the objc_msgSend function to a prototype that matches the method function
> being called.
> This bug can be solved by explicit casting, like so:
> ((void(*)(id, SEL, id))objc_msgSend)(obj, normalSelector, command);
