I'm assuming this is about emacs-lisp-mode.

As you can see, this is not about isearch: re-search-forward behaves the 
same in this regard.

This seems to be a regression from the fix for 
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17325.

Maybe that should just be reverted. A more proper fix would make Emacs 
not consider @ as a symbol constituent when it's the first character. 
The "p" in "_ p" apparently tries but fails to do that.
