Unfortunately, I'm unable to reproduce.

Is it possible that you have a large number of contacts & phone numbers
in your address book?  I only have 74 contacts, and most only have one
phone number.  It's plausible that with enough contacts & phone numbers
the resulting List<string> will contain enough entries that your process
runs out of memory...

You might consider writing each phone number you add to Console.Error
along with a count to see where you're dying (ye olde printf debugging).
Xcode's Organizer's Console tab will show you everything written to
stderr, providing some degree of feedback.
