Issue Description:

Compiler crashes in the MergeSwiftModule step while building a project with the attached files. The crash can be avoided either by merging the two class declarations into a single file, or by renaming the instance/class var "pathComponents" to have a different name.

Important note: this issue can not be reproduced with the default toolchain bundled by Xcode 7.3.1, but it keeps crashing with our development build created from the swift-2.2.1-RELEASE tag.

Assertion failed:
