Can't use Objectiv-c @try @catch @finally syntax at ANE?

I write an ios library and named libDemo.a. When I linked libDemo.a with ANE (Adobe Native Extension) and pacakge the .ane file to .ipa file, the linker fails with some error:

Undefined symbols:

  "_objc_terminate", referenced from:

The error raised from an objective-c source file(named it Demo.m),and the failed function has some code like this:

@try{
...
}
@finally{
...
}

When I comment the @11868606 and @13868228 line,the linker returned with success code.

So,maybe can't use @11868606 @9295854 syntax when the library will be used at ANE enviroments?

Thanks.
