The Swift Compiler crashes with a segmentation fault when generic class inherits from NSObject and conforms to NSObjectProtocol in class extension. This can be easily reproduced with a minimalistic example:
public class D<T>: NSObject {}
extension D: NSObjectProtocol {}
The code above causes the following segmentation fault:
Segmentation Fault: While emitting IR for source file ... ArrayDataSource.swift
