          Issue ID: 22556
           Summary: Invalid GOT load reloc with -O on MacOS
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: moonlightsentinel at disroot.org

The test runnable_cxx/test7925.d consistently fails on MacOS 10.15 (run by
GitHub Actions, see e.g. [1]).
The invalid codegen occurs for the first permutation that includes -O.

Maybe another incarnation of https://issues.dlang.org/show_bug.cgi?id=14814.

 ... runnable_cxx/test7925.d         -fPIC -L-lstdc++ -L--no-demangle (-inline
-release -g -O)
