Description Mats Lidell gentoo-dev 2018-03-12 22:35:09 UTC
Steps to reproduce: 
 - Start 'emacs -Q'
 - M-x list-packages

Filed as upstream bug: Slight difference for the tip version of Emacs where this error occur after only starting with emacs -Q. For 25.3.1 some activity related to hash tables need to be done hence the list-packages.

Comment 1 Andrzej Rybczak 2018-03-13 01:06:57 UTC
Same here. The culprit seems to be fontconfig-2.13.0 as downgrading to fontconfig-2.12.6 solves the problem.
Comment 2 Ulrich Müller gentoo-dev 2018-03-13 11:35:41 UTC
@matsl: Can you confirm that this is related to the fontconfig version?
Comment 3 Mats Lidell gentoo-dev 2018-03-13 17:00:59 UTC
@ulm: Yes. Downgrading to fontconfig-2.12.6 clears the issue.
Comment 4 Ivan Iraci 2018-03-13 17:48:27 UTC
I temporarily solved the issue by aliasing emacs to 'LC_ALL=C emacs'.

Hm, media-libs/fontconfig should be linked against only with USE="xft", but I don't see that flag in your emerge --info output.

(In reply to Ulrich Müller from comment #5)

> I don't see that flag in your emerge --info output.

It's not even in my 'emerge --info', but it's in my package.use.
Maybe the same applies for him.

Anyway, the problem exists and has to do with the locale.

I can reproduce it with LC_NUMERIC=de_DE.UTF-8 but not with LC_NUMERIC=en_US.UTF-8.

Patch for media-libs/fontconfig-2.13.0

Removing the locale initialisation code (which was not present in fontconfig-2.12.6) from function FcConfigEnsure seems to fix it here.
Comment 9 Ulrich Müller gentoo-dev 2018-03-13 21:21:00 UTC
Reported upstream:
Comment 10 Ulrich Müller gentoo-dev 2018-03-13 21:44:55 UTC
@Fonts team: This is major breakage. So unless you raise objections, I am going to package.mask =media-libs/fontconfig-2.13.0 tomorrow.

Please test if this fixes the problem.

Ok, it works for me.

Thank you for your commitment!
Comment 16 Ulrich Müller gentoo-dev 2018-03-14 21:22:17 UTC
Reopening. The following will still trigger the bug:

   $ unset LANG LC_ALL
   $ LC_NUMERIC=de_DE.UTF-8 emacs -Q
