          Issue ID: 21293
           Summary: cxx-headers-test build target segfaults
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Mac OS X
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: doob me.com

Running `./src/build.d cxx-headers-test` results in a segmentation fault on
macOS. Is the invocation of DMD that fails. Running the DMD command (which is
printed when `./src/build.d cxx-headers-test`) inside a debugger results in
this stacktrace:

(lldb) r
Process 40315 launched: 'dlang/dmd/generated/osx/release/64/dmd' (x86_64)
