Didn't hear about these in a while, perhaps several years.
I ran into a porting problem a couple of weeks ago: the Emacs dump approach doesn't work with AddressSanitizer on GNU/Linux, e.g., gcc -fsanitize=address if you're using GCC 4.8 or later. It turns out that John Wiegley reported the problem on emacs-devel in 2012; see: http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00600.html AddressSanitizer would be a useful bug-squasher for Emacs, I expect.
