           Summary: ICE on a variadic function
           Product: DGCC aka GDC
           Version: 0.24
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: glue layer

        ReportedBy: onlystupidspamhere at yahoo.se


This is a simplified piece of code from Tango that segfaults the compiler (I
also tested rev 159) and thus prevents using Tango:

  void c (int f, ...) { c (_arguments, _argptr, f); }


Compiler output:
