Description DJ Delorie 2019-03-21 20:16:36 UTC

This bug was initially created as a copy of Bug #1311954


The binary locale files of glibc should be multilib independent,
but they are not.

Carlos O’Donell: “... the fact that they don't match means there is an upstream ABI bug.”

To test whether they match or not, I did this:

I built glibc from the current f23 branch here:

http://koji.fedoraproject.org/koji/taskinfo?taskID=13113924

Then downloaded:

https://kojipkgs.fedoraproject.org//work/tasks/3923/13113923/glibc-common-2.22-10.fc23.x86_64.rpm
https://kojipkgs.fedoraproject.org//work/tasks/3924/13113924/glibc-common-2.22-10.fc23.i686.rpm

unpacked the rpms and checked whether locale-archive.tmpl differ.

They do differ:

mfabian@ari:~/tmp/glibc-locale-subpackaging
$ diff {i686,x86_64}/usr/lib/locale/locale-archive.tmpl
Binary files i686/usr/lib/locale/locale-archive.tmpl and
x86_64/usr/lib/locale/locale-archive.tmpl differ
mfabian@ari:~/tmp/glibc-locale-subpackaging
$

And not only a little bit:
mfabian@ari:~/tmp/glibc-locale-subpackaging
$ cmp -l {i686,x86_64}/usr/lib/locale/locale-archive.tmpl |wc
3084277 9252831 55516986
mfabian@ari:~/tmp/glibc-locale-subpackaging
$

Comment 1 Florian Weimer 2019-03-25 07:38:49 UTC

Note that we build glibc in Red Hat Enterprise Linux 8 using -msse2 -mfpmath=sse, so the discrepancy should not materialize there because excess precision is avoided due to the use of SSE2 (on both i686 and x86_64).

Comment 4 Sergey Kolosov 2019-09-11 11:08:29 UTC

Verified, the file /usr/lib/locale/locale-archive.tmpl is the same on i686 and x86_64 architectures.
