            Bug ID: 20467
           Summary: Default -fmodules-cache-path is not made
                    world-writable, breaks if multiple users use modules
                    on same system
           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

    Classification: Unclassified

The implicitly-generated module cache doesn't work for multi-user systems;
building modules silently fails if the module cache path is owned by a
different user. (Tested on x86_64 linux.)
