Looks very similar to SR-9101. @millenomi?

I'm facing something similar too

Segmentation fault with the following code

Swift version 5.0 (swift-5.0-RELEASE)

Target: x86_64-unknown-linux-gnu

Ubuntu 18.04.2 LTS (Bionic Beaver)

Swift Official Image running on a Docker container

thanks @belkadan, indeed! That is also a NULL CFLocale which looks like SR-10333.

This is a dupe of SR-10333 and was fixed in #2067
