[PATCH] D74488: [VFS] Fix vfsoverlay assertion due to RedirectingFileSystem path handling.

[Adrian McCarthy via Phabricator via llvm-commits]

amccarth added a comment.

> FileManager::FixupRelativePath uses path::append to append "." onto the working directory and gets "C:/work/example\." because path::append uses the preferred native separator which is "\"

This is where we diverge.  I'm getting a Windows-style working directory (`C:\work\example`), so appending the dot yields `C:\work\example\.`, and canonicalize handles that properly.

The working directory is initialized from the external filesystem.  On my machine, this is naturally in native host form.  In your case, something must be changing it to the (forward) slash form.

Still investigating.
