From commit bdb2d56ee (gnu: mutt: Update to 1.6.1.), I applied a patch
from guix-devel [0], tried to build a package, and got a backtrace as
shown below.

I had rebuilt from the git tree recently, but I'm not sure exactly when.

It goes away after I rebuild.

Why is this file being loaded, instead of scripts/guix?  Could it be
that scripts/guix was missing at that time?

Maybe it would be wise to apply a patch as attached to prevent such
situations from arising.  WDYT?

Thanks,
Ludo’.

It happened again, and scripts/guix was present. Next time I will take a
snapshot of the broken state.

Any updates?  :-)

I've noticed that it happens if I do this:

$ guix gc && ./pre-inst-env guix build foo

If I then do the following, it works again:

$ guix environment guix
$ exit
$ ./pre-inst-env guix build foo 

I don't have all of the Guix dependencies in my profile or my Debian
environment (I see this on my Debian machine), so I guess that something
important is garbage collected, but I haven't figured out what yet.

So, I think it's not much of a bug, since I am deliberately invoking the
garbage collector. WDYT?

Possibly.  If you use ./configure -C, the ‘config.cache’ file also gets
stale after GC.  But even if you don’t, (guix config) might be referring
to things that have been collected, so you have to:

  rm -f config.cache && ./configure

I’m closing this bug, but do reopen it if you think something’s really
broken.  :-)

Thanks!
