This is not classic related, it also happens on Unified 32-bit.

3.4 as well as 3.6.
Comment 2 Chris Hamons 2017-07-12 17:35:04 UTC
This appears to be an Apple regression from b2 to b3:

An obj-c app with the following code:

    CLLocationManager * mgr = [[CLLocationManager alloc] init]; (In a loaded proc in obj-c)

crashes in b3 but not b2 when run on a 32-bit Cocoa app.

Radar coming up soon.

Radar filed. 

Given the likely high visibility of this, I filed it also on open radar:

Comment 5 Chris Hamons 2017-07-12 19:06:12 UTC
From radar: CoreLocation depends on a private framework GeoServices which invoke initCNPostalAddressStreetKey at static initializer time even in 32-bit, but Contacts which I assume it is setting up is 64-bit only.

This was fixed by Apple in Beta 4.

QA - This does not need validation.
