Bug ID: 16915
Summary: nl_langinfo doesn't work with static linking
Product: glibc
Version: 2.13
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: aurelien at aurel32 dot net
CC: drepper.fsp at gmail dot com
When used in statically linked binaries, nl_langinfo() does not work for some
categories, as it can be seen with a small example like that:
#include <stdio.h>
#include <locale.h>
#include <langinfo.h>
int main(void)
{
setlocale (LC_ALL, "fr_FR.UTF-8");
printf("%s\n",nl_langinfo(DAY_2));
return 0;
}
Such a code returns "Monday" instead of "lundi" when compiled dynamically.
A patch is available on
http://sourceware.org/ml/libc-alpha/2014-05/msg00134.html

Fix strtold on 32-bit sparc (and probably others) (BZ #16965)
This patch fixes an issue observed running the tst-strtod-round test on
32 bit sparc. In some conditions, strtold calls round_and_return, which in
turn calls __mpn_rshift with cnt = 0, while stdlib/rshift.c explicitly says
that cnts should satisfy 0 < CNT < BITS_PER_MP_LIMB. In this case, the code
end up doing a logical shift right of the same amount than the register,
which is undefined in the C standard.
Due to this bug, 32-bit sparc does not correctly convert the value
"0x1p-16446", but it is likely that other architectures are also
affected for other input values.

fix nl_langinfo with static linking (BZ #16915)
For static linking the locale code avoids linking code and data for
unused categories. However for nl_langinfo we know only at runtime which
categories are used, so direct reference to every nl_current_CATEGORY
symbol should be done.
This was broken by commit bc3e1c127392da88d0c8bf2ae728147982a3d1bc where
nl_langinfo_l and nl_langinfo have been merged and some code has been
lost in the process.
In order to detect locales issues with static linking, compile a version
of tst-langinfo with static linking.
Note: this is Debian bug#747103 reported by Raphael
