I can reproduce this: it seems to be eating one character each time it is
executed at the end of the #+END_LaTeX. Here's a patch that seems to fix
this problem - however, it is not based on any real understanding of the code,
so take it with a grain of salt. Also, if this fix works, then it is likely
that the other "wrap" cases will also need similar treatment:
diff --git a/lisp/ob.el b/lisp/ob.el
