          Issue ID: 14871
           Summary: Linker errors with 2.068.0-rc1
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Keywords: industry, link-failure
          Severity: regression
          Priority: P1
         Component: dmd

While testing 2.068.0-rc1 against some EMSI internal code as well as a
development version of DCD I ran into some linking issues. It seems that the
linker is trying to resolve some symbols whose names end with "__arrayZ" and
"__assertFiZv". These symbol names seem to always be at module scope.

Example error messages:

/path_partially_redacted/ext/containers/src/containers/unrolledlist.d:445:
undefined reference to `_D10containers12unrolledlist8__assertFiZv'

bin/dcd-server.o: In function

It should be possible to reproduce part of the error with a checkout of DCD at
this version:

(Remember to run `git submodule update --init --recursive after checking out)
