While working on reproducible builds for openSUSE, I found that
one file in the maildir-utils package randomly differed (50% of time)

/usr/share/emacs/site-lisp/mu4e/mu4e-view.elc differs at offset '32229' (Emacs/X
Emacs v23 byte-compiled Lisp data)

Problem goes away with this patch to the .spec file:
-make %{?_smp_mflags}
+make -C lib %{?_smp_mflags}
+make

but this type of issue could indicate poorly defined dependencies/ordering
or maybe there is a race condition somewhere?

Comment 2 Michael Vetter 2019-03-05 10:22:55 UTC
I still don't understand why it happens.
But will build the package for now with:

> make -C lib %{?_smp_mflags}
> make

12% time difference when I tested.
