A fresh checkout builds "OK", for the following value of "OK": After
doing ./configure and make bootstrap, the build crashes with
(presumably) a segmentation fault (it said "error 6", or something
similar). After doing "make" ~10 times, emacs was built. At each
attempt, it crashed with a seg fault. I think there's a memory leak
here, but I've said that already.

Thanks!

It doesn't appear in my new-checkout build, but it does in my usual
Emacs-23, in respect of files
em-{alias,banner,basic,cmpl,dirs,glob,hist,ls,pred,prompt,rebind,script,smart,term,unix,xtra}.el.
In fact, that's pretty much every lisp file which has ;;;###autoloads.
Somehow, autoload.el is failing to redirect the autoloads to the correct
output file (here, eshell/esh-groups.el).

Apologies. I inserted ";;;###autoload" on eshell-defgroup myself, in an
attempt to get things working, then forgot about it and got thoroughly
confused.

Ah, right, I see.

Yes. But I'm so sick and fed up of not being able to build routinely, I
am going to track down this problem even if it takes me weeks to do it.
I am not prepared to check out the sources from scratch every time I
can't get a build working.
Refactoring autoload.el might be a good first move.

Thanks for taking the time to put me right! I hope you're enjoying it!
