After updating today, I started emacs -Q and tried to visit a file in my
CVS Emacs tree, and this raised a wrong-type-argument error. This
happens with any file under version control. It does not happen with my
previous build from two weeks ago. A backtrace is attached (because it
contains byte code)

In fact it seems to happen with any file, and with some libraries that
write files to disk on exiting, such as Gnus, this makes it impossible
to exit Emacs normally, only kill -9 works. I reverted to a week old
revision in order to get a working Emacs.

It's the bug I referred to earlier in emacs-devel about CL functions.
Just "re lisp/vc-hooks.elc; make" should fix it for now.
What happens is that vc-hooks.el ended up byte-compiled in a context
where subr.el was loaded after cl.el, so while CL was loaded, the `push'
macro was not the CL one but the plainer one provided by subr.el.
And of course vc-hooks.el uses some of CL's added features of `push'.
