          Issue ID: 12836
           Summary: CTFE ICE CompiledCtfeFunction::walkAllVars
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com
          Reporter: ibuclaw at gdcproject.org

This is similar to #12397 and I'd imagine the same fix will apply to both, but
the test case is different enough that it warrants a new issue.
