XMPPvCardTempEmail exits process on +initialize()

[Germandrummer92]

Hi,

we're dealing with vCards right now. The XMPPvCardTempEmail class is broken on XCode 9.2 with iphone 5s (or newer models). This basic XCTest fails:

import XCTest  
import XMPPFramework

class XMPPvCardTempEmailTest: XCTestCase { 
  
    func testXMPPvCardEmail() {  
        _ = XMPPvCardTempEmail(name: "Hello", numberValue: 1)  
    }  
  
} 

Error Message:

2018-04-11 15:04:54.487509+0200 Messenger[96373:4956473] Adding instance variables to XMPPvCardTempEmail is not currently supported!

The failing check (after debugging):

size_t superSize = class_getInstanceSize([NSXMLElement class]); //size is 24
	size_t ourSize   = class_getInstanceSize([XMPPvCardTempEmail class]); //size is 32
	
	if (superSize != ourSize)

We think it's a 64 bit issue, but didn't have a readily available 32 bit setup, so not 100 % sure.
