GNU C Library version 2.6.1 release

Hash: SHA1

Version 2.6.1 of the GNU C Library is now available for download at:

Please see and for mirror sites around the world.

This is a bug-fix release intended only for those using stable systems
already based on the version 2.6 release.  If you are building a new
system from scratch, please use version 2.6.1 instead.

The 2.6 and 2.6.1 releases of the GNU C Library are licensed under the
LGPL version 2.1, and GPL version 2.1 for the non-library programs
included, or any later version.  This means you are free to redistribute
this version under the terms of the LGPL version 3 or the GPL 3, as well
under as the version 2.1 terms of the 2.6 release.  We expect that the
next non-bug-fix release of the C Library will migrate to a newer LGPL version.

The following bugs are resolved with this release:

4512, 4514, 4525, 4586, 4702, 4745, 4858

Visit <> for the details of each bug.

The version 2.6 release had a bug in the `malloc_set_state'
function that broke ABI compatibility with previous versions.
For any program using this function, a binary built against
version 2.5 or earlier would be broken when running with a
version 2.6 shared library.  This may have been worked around
by recompiling against the version 2.6 library, however this
created a binary depending on the binary-incompatible bug.
System distributions using version 2.6 fixed this problem in
their released shared libraries, so most users will not have
been affected by version 2.6's misbehavior.  This bug is now
fixed in version 2.6.1, so that a 2.6.1 shared library is
compatible with old binaries built with version 2.5 or earlier.
However, this means that any binaries rebuilt against an
unmodified 2.6 shared library had this 2.6 bug built in and are
thus incompatible with a 2.6.1 shared library.

Be advised that updating the C library is no trivial task and it is very
easy to damage one's system.  Unless you are participating in the
development and maintenance of the C library, you should use a binary
distribution instead.  The code in this release has already been built
and tested by maintainers of binary distributions basing their systems
on it.  If you are not already using a system based on the version 2.6
ABI, then you may wreak havoc by attempting to install this version.

GCC version 4.1 or later is required to build version 2.6 of the C library.

The glibc-libidn files have not changed from the 2.6 version.
If you are using a configuration supported by the use of
glibc-ports-2.6 files and have issues, please contact the

This release like all others was made possible by the contributions of many
people, this time primarily Ulrich Drepper and Jakub Jelinek.
