Valgrind is a tool that helps you find memory management problems in programs. When a program is run under Valgrind's supervision, all reads and writes of memory are checked, and calls to malloc/new/free/delete are intercepted. As a result, Valgrind can detect problems such as use of uninitialized memory, reading/writing of memory after it has been freed, reading/writing off the end of malloced blocks, reading/writing inappropriate areas on the stack, memory leaks in which pointers to malloced blocks are lost forever, passing of uninitialized and/or unaddressable memory to system calls, and mismatched use of malloc/new/new  vs. free/delete/delete .

Release Notes: This is a bugfix release. It fixes some assertion failures in 3.8.0 that occurred moderately frequently in real use cases, adds support for some missing instructions on ARM, and fixes a deadlock condition on Mac OS X.
Release Notes: This release adds support for ARM/Android, S390X/Linux, and Mac OS X 10.7 (Lion). A GDB server has been added, so you can now control your application from inside GDB while it runs on Valgrind. There have been performance and functionality improvements for Helgrind, DRD, Memcheck, and exp-Sgcheck. The tool formerly known as exp-Ptrcheck has been renamed to exp-SGCheck. This release supports X86/Linux, AMD64/Linux, ARM/Linux, PPC32/Linux, PPC64/Linux, S390X/Linux, ARM/Android (2.3.x), X86/Darwin, and AMD64/Darwin (Mac OS X 10.6 and 10.7).
Release Notes: This is a feature release with many significant improvements and the usual collection of bug fixes. The main improvement is that Valgrind now works on ARM/Linux and on Mac OS X 10.6 (Snow Leopard).
Release Notes: Improvements and simplifications of the leak checker. Clarification and simplifications of text output. Helgrind and Ptrcheck now give XML output. Helgrind and DRD have improved stability and performance. Genuinely atomic support for x86/amd64/ppc atomic instructions. A new experimental tool, BBV, useful for computer architecture research. Support for Mac OS X. Improved Wine support, including ability to read Windows PDB debuginfo.
Release Notes: This release 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.
