           Summary: ICE when object.d is missing things
           Product: DGCC aka GDC
           Version: unspecified
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: glue layer
        AssignedTo: dvdfrdmn at users.sf.net
        ReportedBy: madou at madou.org


cc1d segfaults when trying to compile an object.d source file that's missing
certain things, instead of giving a an error message. An object.d file
containing only an empty Object class is the simplest test case that reproduces
the error.


--------- object.d ---------

class Object
{
}

Program received signal SIGSEGV, Segmentation fault.
