We are pleased to announce a new release of Valgrind, version 3.4.1,
available from http://www.valgrind.org. See the attached release
notes for details.
Happy (and productive) debugging and profiling,
-- The Valgrind Developers
Release 3.4.1 (28 February 2009)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.4.1 is a bug-fix release that fixes some regressions and assertion
failures in debug info reading in 3.4.0, most notably incorrect stack
traces on amd64-linux on older (glibc-2.3 based) systems. Various
other debug info problems are also fixed. A number of bugs in the
exp-ptrcheck tool introduced in 3.4.0 have been fixed.
In view of the fact that 3.4.0 contains user-visible regressions
relative to 3.3.x, upgrading to 3.4.1 is recommended. Packagers are
encouraged to ship 3.4.1 in preference to 3.4.0.
The fixed bugs are as follows. Note that "n-i-bz" stands for "not in
bugzilla" -- that is, a bug that was reported to us but never got a
bugzilla entry. We encourage you to file bugs in bugzilla
(http://bugs.kde.org/enter_valgrind_bug.cgi) rather than mailing the
developers (or mailing lists) directly -- bugs that are not entered
into bugzilla tend to get forgotten about or ignored.
n-i-bz Fix various bugs reading icc-11 generated debug info
n-i-bz Fix various bugs reading gcc-4.4 generated debug info
n-i-bz Preliminary support for glibc-2.10 / Fedora 11
n-i-bz Cachegrind and Callgrind: handle non-power-of-two cache sizes,
so as to support (eg) 24k Atom D1 and Core2 with 3/6/12MB L2.
