Including BaseMath in Xcode project crashes build

[porterchild]

Not sure if I'm doing something wrong or things just haven't been updated in a while, but when I try to use BaseMath in an Xcode project (toolchain 11.3.1), BaseMath produces a Segmentation Fault while building. I also tried using SwiftyMKL but it didn't build, probably because it depends on BaseMath.

Output:
