Issue with Swift 2.2 generics (Xcode 7.3)

I've got a frustrating situation with Swift 2.2 (Xcode 7.3). To simulate it, just create a variable in a user defined, generic class, and reference that class from someplace else. For example:

class A<T> {
    let genVar = 1
}

class MyViewController: UIViewController {
    let myVar = A<Int>() // crash is here
}

If you will run this code on a device running iOS 7 (iPhone 4, in my case), it will crash on the attempt of creating a variable of generic type. Here are the first lines of the device crash log:

Exception Type:  EXC_BAD_ACCESS (SIGBUS)

On iOS 8 and 9 simulators/devices, the code above works okay.

Is Swift support for iOS 7 going to be dropped in the near future?
