There is a file test.c in the root directory.
Command 'clang /test.c' produces following error:

error: error reading '/test.c'
1 diagnostic generated.

The file exists and has read access for everyone.
The issue is probably in FileManager.cpp:getDirectoryFromFile(). It produces
invalid input for FileMgr.getDirectory().
