Very hard to say without more details.  Like whether this was the
first character of a buffer/string for which the function
bidi_move_to_visually_next was called, what kind of object (buffer,
string, composition, something else) we were iterating, what is the
contents of the bidi_cache, etc.

A reproducer is best, of course.
