When I compile the following test program, I get a segmentation violation.
When the structure declaration is removed from the class, the problem goes away.

>>> The code:
/*  g++ 1.35.0, sun3-os4; signal 11 while compiling */
class ObjectTable 
	{
	
private:

	typedef struct ote_struct
		{
		int x;
		int y;
		} ObjectTableElement;

	ObjectTableElement ote;

	ObjectTableElement* index() { return &ote; }

public:
	void     setNBytes();
	};

>>> The compiler messages:

Fix: in cplus-search.c (dfs_pushdecls):

  for (fields = TYPE_FIELDS (type); fields; fields = TREE_CHAIN (fields))
    {
      /* Unmark so that if we are in a constructor, and then find that
	 this field was initialized by a base initializer,
	 we can emit an error message.  */
      TREE_USED (fields) = 0;
      if (DECL_ANON_UNION_ELEM (fields))
	{
	  dfs_pushdecls (TREE_TYPE (fields));
	  continue;
	}
+      if (TREE_CODE (fields) == TYPE_DECL)
+	continue;
