[Valgrind-announce] valgrind-3.2.1 for {x86, amd64, ppc32, ppc64}-linux is available

[Julian S. <js...@ac...>]

A bug-fix release of valgrind, version 3.2.1, is now available from
http://www.valgrind.org.  See the attached release notes for details.

Happy (and productive) debugging and profiling,

-- The Valgrind Developers


Release 3.2.1 (16 Sept 2006)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.2.1 adds x86/amd64 support for all SSE3 instructions except monitor
and mwait, further reduces memcheck's false error rate on all
platforms, adds support for recent binutils (in OpenSUSE 10.2 and
Fedora Rawhide) and fixes a bunch of bugs in 3.2.0.  Some of the fixed
bugs were causing large programs to segfault with --tool=callgrind and
--tool=cachegrind, so an upgrade is recommended.

In view of the fact that any 3.3.0 release is unlikely to happen until
well into 1Q07, we intend to keep the 3.2.X line alive for a while
yet, and so we tentatively plan a 3.2.2 release sometime in December
06.

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.

n-i-bz   Expanding brk() into last available page asserts

         --collect-jumps=yes
n-i-bz   docs path hardwired (Dennis Lubert)

The following bugs were not fixed, due primarily to lack of developer
time, and also because bug reporters did not answer requests for
feedback in time for the release:

129390   ppc?->IR: some kind of VMX prefetch (dstt)
129968   amd64->IR: 0xF 0xAE 0x0 (fxsave)
133054   'make install' fails with syntax errors

n-i-bz   Unrecognised instruction at address 0x70198EC2 (users list,
         19 July, Bennee)
132998   startup fails in when running on UML

The following bug was tentatively fixed on the mainline but the fix
was considered too risky to push into 3.2.X:

133154   crash when using client requests to register/deregister stack

(3.2.1: 16 Sept 2006, vex r1658, valgrind r6070).
