Compiler crash on internal Foundation import

[mr-swifter]

Description

During development I accidentally added internal import of Foundation library. The product/target itself compiles normally, but compilation of target which depends on that target fails with a compiler crash.

Reproduction

internal import Foundation

and compile any dependant target. if remove internal keyword the program compiles normally.

Actually it also happens in my project on regulate import of dependency target, not only internal import.
