Issue Description:

The swift compiler with versions 5.1.3, 5.2 crashes if you run any project containing C/C++ dependencies with --repl attribute: `swift run --repl`.

This behavior appears on macOS only, on Ubuntu 18 same packages works well in the same situation. The crash appears on import Swift Package that contains the C/C++ dependencies into repl.

  • The `swift test` command within the same setup works properly.

  • The same project, but as executable (e.g. MyLibrary.swift renamed to main.swift) works properly with `swift run` command.

Steps to reproduce:

  1. `swift package init --type library MyLibrary`.
    2.1 Add the following dependency to the package dependencies: `.package(url: "https://github.com/swift-server/async-http-client.git", from: "1.0.0")`.
    2.2 Add follow dependency to MyLibrary target dependencies: `.product(name: "AsyncHTTPClient", package: "async-http-client"),`.
  2. Run `swift run --repl`.
  3. In swift console console type: `import MyLibrary`.

Expected behavior:

Package loads and its public types and methods are available within repl runtime.

Current behavior:

Repl crashes with the following stacktrace:

warning: Swift error in fallback scratch context: <module-includes>:1:9: note: in file included from <module-includes>:1:
 #import "/Volumes/devel/Programming/swift/CourtParser/.build/checkouts/swift-nio-ssl/Sources/CNIOBoringSSLShims/include/CNIOBoringSSLShims.h"

 ^
error: could not build Objective-C module 'CNIOBoringSSLShims'
note: This error message is displayed only once. If the error displayed above is due to conflicting search paths to Clang modules in different images of the debugged executable, this can slow down debugging of Swift code significantly, since a fresh Swift context has to be created every time a conflict is encountered.
