I recently encountered this undesirable side-effect when using the
https://github.com/emacscollective/auto-compile library in conjunction
with a byte-compiled init file.  The combination is reliably resulting
in `user-init-file' being set to the .../lisp/progmodes/compile.el.gz
path, with ensuing chaos (e.g. customized settings being written to
that file -- I first became aware of this problem while using emacs -Q
when it suddenly acquired some custom faces from my regular config as
something loaded the compile library!).

The purpose of the auto-compile package is to ensure that .elc files
are always up-to-date and loaded in preference to .el files.  I've been
using it for many years and wasn't aware of having had any issues with
it in the past, but I do not typically have a byte-compiled init.elc
file.  The auto-compile code advises `load' and `require' (which does
seem like it could present risks), however it seems so very odd to me
that user-init-file could end up with this value for any reason that
it seems like it might ultimately be an Emacs bug.

I raised it with the auto-compile maintainer (Jonas Bernoulli, CC'd)
at https://github.com/emacscollective/auto-compile/issues/33 and we
couldn't make sense of it at the time, so I'm escalating it here.

The attached bash shell recipe reproduces the issue in Emacs 29.
I can reproduce it in all of Emacs 27, 28, 29, 30 (and not 26.3 or
25.3), but this recipe uses the --init-directory option which was
added in 29.1.

(See attached script.)

The echo area in the final instance of Emacs should report the path to
compile.el.gz (and re-running the final "touch init.el && ..." command
will repeat that result each time).


If I put (debug) at the top of compile.el.gz then I get the following
backtrace, so we can see how/why compile.el is getting involved, but
it just seems very wrong for that path to be able to end up being the
user-init-file value.


Debugger entered: nil
   byte-code(...)
   compilation-mode()
   emacs-lisp-compilation-mode()
   byte-compile-log-file()
   byte-compile-from-buffer(#<buffer  *Compiler Input*>)
   byte-compile-file("/tmp/autocomp/init.el")
   auto-compile--byte-compile-file("/tmp/autocomp/init.el")
   auto-compile-on-load("/tmp/autocomp/init" nil)
   load@auto-compile("/tmp/autocomp/init" noerror nomessage)
   apply(load@auto-compile ("/tmp/autocomp/init" noerror nomessage))
   load("/tmp/autocomp/init" noerror nomessage)
   startup--load-user-init-file(#f(compiled-function () #<bytecode

-0xe2e004ca56aeafc>) t)
   command-line()
   normal-top-level()


As it seems to have started in Emacs 27, my *guess* is that it's
connected to the early-init.el system which was added in Emacs 27,
but I've not dug any further at this stage.
