I have C application with a structure that has a named union, i.e., 


typedef struct t_GTD
{
    union {
        struct {
             t_V2D       intercept;
        } ellipse;
        struct {
            double  	Q2;
            double  	W2;
         } torus;
        struct {
            double  	c0;
            double  	c1;
            double  	c2;
            double  	c3;
        } lor;
    } u; 
}  t_GTD;

When I reference this structure, VAX correctly suggests u and incorrectly suggests ellipse, torus and lor. Since they're presented alphabetically (and I forget about the u), I select the inner field (e.g., GTD->ellipse) and then get a bunch of compilation errors.

If you move the structure and union names to the beginning, like this, then the problem goes away. Of course, this might work more easily if you were compiling in C++

typedef struct t_GTD
{
	union u {
		struct ellipse {
			t_V2D       intercept;
		} ;
		struct torus {
			double  	Q2;
			double  	W2;
		} ;
		struct lor {
			double  	c0;
			double  	c1;
			double  	c2;
			double  	c3;
		} ;
	} ; 
}  t_GTD;

case=3548 is a similar issue to case=4514, and is fixed in build 1845
