Only if it saves in a dump with one and restores with the other, isn't
it? Actually, I can't see how it matters at all. I may have to
grovel through the emacs dumper to try to figure it out.
Meanwhile, mallocing anything containing a long double or vector
generates quietly wrong code unless you use posix_memalign :-(
