Question: What is the exact meaning of the different arrow shapes in objdump output?

Do you have an example of these effects that we could examine ?

Presumably the + character is meant to imply crossing lines and the X
character is meant to imply that multiple lines intersect at this
location.  But it is also entirely possible that you have run into a
bug and the visualization code is using the wrong characters.
