Hi,

Given an IDL file which contains a typedef of an interface being used as
a member of an exception. For example:

  interface RefObject {};

  typedef RefObject DesignatorType;

  exception myError {
    DesignatorType designator;
  };


The omniORB 2.8.0 idl compiler will core dump.

I think the attached patch will fix the bug.

Doug.
