            Bug ID: 20468
           Summary: permission error while loading module map is not
                    diagnosed
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Modules
          Assignee: unassignedclangbugs at nondot.org
          Reporter: richard-llvm at metafoo.co.uk
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

If a module map points to a file that the current user can't read, the module
is silently ignored, potentially resulting in weird silent breakage. Instead,
we should issue a diagnostic in this case.
