People who first bump into this with Emacs 25.1 will have 25.2 soon enough (I hope). By contrast, those who will try to build Emacs 24.x on the newer GNU/Linux systems will be unable to resolve the instability problems exposed by using ralloc.c, except by back-porting patches we have just committed to the Emacs repository, which is not easy. Not sure what to do with the old versions, or whether anything can be done.
