"Updated glibc packages that address several bugs and implement some
enhancements are now available.

The GNU libc packages (known as glibc) contain the standard C
libraries used by applications.

This errata fixes several bugs in the GNU C Library.

Fixes include (in addition to enclosed Bugzilla entries) :

  - fixed 32-bit atomic operations on 64-bit powerpc - fixed
    -m32 -I /usr/include/nptl compilation on AMD64 - NPTL
    <pthread.h> should now be usable in C++ code or
    -pedantic -std=c89 C - rwlocks are now available also in
    the _POSIX_C_SOURCE=200112L namespace - pthread_once is
    no longer throw(), as the callback routine might throw -
    pthread_create now correctly returns EAGAIN when thread
    couldn't be created because of lack of memory - fixed
    NPTL stack freeing in case of pthread_create failure
    with detached thread - fixed pthread_mutex_timedlock on
    i386 and AMD64 - Itanium gp saving fix in linuxthreads -
    fixed s390/s390x unwinding tests done during
    cancellation if stack frames are small - fixed
    fnmatch(3) backslash handling - fixed out of memory
    behaviour of syslog(3) - resolver ID randomization -
    fixed fim (NaN, NaN) - glob(3) fixes for dangling
    symlinks - catchsegv fixed to work with both 32-bit and
    64-bit binaries on x86-64, s390x and ppc - fixed
    reinitialization of _res when using NPTL stack cache -
    updated bug reporting instructions, removed glibcbug
    script - fixed infinite loop in iconv with some options
    - fixed inet_aton return value - CPU friendlier busy
    waiting in linuxthreads on EM64T and IA-64 - avoid
    blocking/masking debug signal in linuxthreads - fixed
    locale program output when neither LC_ALL nor LANG is
    set - fixed using of uninitialized memory in localedef -
    fixed mntent_r escape processing - optimized mtrace
    script - linuxthread_db fixes on ppc64 - cfi
    instructions in x86-64 linuxthreads vfork - some
    _POSIX_C_SOURCE=200112L namespace fixes

All users of glibc should upgrade to these updated packages, which
resolve these issues."
