Hi Rui, thanks for spotting this.

I am not a maintainer, so I can only comment.

I do not think this patch applies cleanly to the master branch, but the 
change should be trivial.  That being said, it is true that 
find_pc_partial_function returns the first address past the end of the 
function, so the change looks good to me.  Thanks for spotting this!

Best,
Lancelot.
