[Valgrind-announce] Valgrind-2.4.1 is available

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

We are pleased to announce a new stable release of Valgrind, version
2.4.1.  It is available from http://www.valgrind.org.

Valgrind is an award-winning open-source suite of simulation based
debugging and profiling tools.  With the tools that come with
Valgrind, you can automatically detect many memory management bugs,
avoiding hours of frustrating bug-hunting, and make your code more
stable.  You can also perform detailed time and space profiling to
help speed up and slim down your programs.

2.4.1 is a maintenance release that contains various bug fixes which
have accumulated since 2.4.0 was released about four months ago.
Details are below.

2.4.1 still only supports x86-linux.  For amd64-linux support, please
wait for 3.0, which will ship shortly.

Many thanks to Dirk Mueller for coordinating the 2.4.1 release.

Happy (and productive) debugging and profiling,

-- The Valgrind developers


New in 2.4.1 vs 2.4.0
~~~~~~~~~~~~~~~~~~~~~
- fixed regression in stabs parsing introduced by fixing bug 90128

- major performance fix by Pete Moceyunas to improve malloc handling

- several smaller fixes to the code, as detected in a code analysis
  performed by Madhu Kurup using the "Prevent" Stanford code checker

- bug in VG_(atoll36) fixed -- this might have been causing some
  failures in C++ name demangling

- fixed double free in reading ~/.valgrindrc

- removed irrelevant linker version script that broke compilation with
  newer binutils.

- fixes for the following bugs:
  88678:  fix debug info for file names containing spaces
  106713: preserve %esi accross calls to clone.
  103509: times(NULL) gets incorrect unaddressable bytes warning
  106293: fix stack-scanning in VALGRIND_DO_LEAK_CHECK
  104797: handle BLKGETSIZE64 ioctl
  101881: segfault when command-line-args are in RO-memory

- fix valgrind crash when no environment is given to an execve() call

- disable PIE compilation by default. It caused too many non-working
  builds and accordingly many bugreports.

- fix stabs debug info reading for FreePascal binaries

- update syscall table to include new syscalls included in Linux
  2.6.13.

- updates to compile properly with gcc 4.x and glibc 2.4

New features:

The macros VALGRIND_STACK_REGISTER, VALGRIND_STACK_DEREGISTER and
VALGRIND_STACK_CHANGE have been added. These can be used to inform
valgrind about stack switches, if your application uses userland
threading libraries.
