Crash in FTD

[jodyscho]

I found this crash in our POS app store build. Couldn't get more info than this but this at least has filenames and line numbers that might help locate the problem.

This should be fixed by Swift 4.2. There were a few optimizer bugs that caused problems in the 4.1 release.
