But here is the reduced testcase which I got:
struct xobject {
char type;
};
extern struct xobject *t1_Xform ( struct xobject *obj);
struct xobject *
t1_Xform(struct xobject *obj)
{
register struct font *F = (struct font *) obj;
return((struct xobject*)F);
}
: Search converges between 2004-09-14-trunk (#539) and 2004-09-15-014001-trunk (#540).
And I have a fix as I caused it.
