bug#23739: Unexpected behavior of 'add-to-load-path'.

[Mathieu Lirzin]

Hello,

I have noticed something that doesn't feel right when using
‘add-to-load-path’.

$ cat test.scm
--8<---------------cut here---------------start------------->8---
(define old %load-path)
(add-to-load-path "foo")
(pk %load-path)
(pk old)
--8<---------------cut here---------------end--------------->8---

first run:

$ guile test.scm
--8<---------------cut here---------------start------------->8---
;;; [Compilation]
;;; (("foo" "foo" "/usr/share/guile/2.0" "/usr/share/guile/site/2.0" "/usr/share/guile/site" "/usr/share/guile"))

;;; (("foo" "/usr/share/guile/2.0" "/usr/share/guile/site/2.0" "/usr/share/guile/site" "/usr/share/guile"))
--8<---------------cut here---------------end--------------->8---

next runs:

$ guile test.scm
--8<---------------cut here---------------start------------->8---
;;; (("foo" "/usr/share/guile/2.0" "/usr/share/guile/site/2.0" "/usr/share/guile/site" "/usr/share/guile"))

;;; (("/usr/share/guile/2.0" "/usr/share/guile/site/2.0" "/usr/share/guile/site" "/usr/share/guile"))
--8<---------------cut here---------------end--------------->8---

each time test.scm is recompiled the first result reappears.  This has
been tested with Guile 2.0.11 and Guile master.

Thanks,

I can confirm half of it :-)

I mean: the double entry "foo" for %load-path in your first result
above doesn't happen for me. Could that be a typo?

As for the strangely different behaviour when running pre-compiled
(old has %load-path's old value) and compiling (old has %load-path's
value after (add-to-load-path ...) yes, that happens to me too, on

  tomas@rasputin:/tmp$ guile --version
  guile (GNU Guile) 2.0.11.133-d680
  Copyright (C) 2014 Free Software Foundation, Inc.

Looks like a bug to me.

My report was partially correct indeed.  There are two added entries in
‘%load-path’ with Guile from Debian testing:

$ guile --version
guile (GNU Guile) 2.0.11
Packaged by Debian (2.0.11-deb+1-10+b1)
Copyright (C) 2014 Free Software Foundation, Inc.

but only one with guile master:

$ meta/guile --version
guile (GNU Guile) 2.1.2.191-6788f
Copyright (C) 2016 Free Software Foundation, Inc

OK, so the only remaining issue is the 'auto-compile' part.

Thanks for the information.
