Memory Management Debugger
Valgrind checks all memory operations in an application, like read,
write, malloc, new, free, and delete. Valgrind can find uses of
uninitialized memory, access to already freed memory, overflows,
illegal stack operations, memory leaks, and any illegal
new/malloc/free/delete commands. Another program in the package is
"cachegrind," a profiler based on the valgrind engine.
To use valgrind you should compile your application with "-g -O0"
compiler options. Afterwards you can use it with:
valgrind --tool=memcheck --sloppy-malloc=yes --leak-check=yes
--db-attach=yes my_application, for example.
More valgrind options can be listed via "valgrind --help". There is
also complete documentation in the /usr/share/doc/packages/valgrind/
directory. A debugged application runs slower and needs much more
memory, but is usually still usable. Valgrind is still in development,
but it has been successfully used to optimize several KDE applications.

(revision 3)
- update to 3.22.0: (jsc#PED-5442):
* Memcheck now tests and warns about the values used for
alignment and size. These apply to various functions: memalign,
posix_memalign and aligned_alloc in C and various overloads
of operators new and delete in C++. The kinds of error that can
be detected are
- invalid alignment, for instance the alignment is usually required
to be a power of 2
- mismatched alignment between aligned allocation and aligned
deallocation
- mismatched size when sized delete is used
- bad size for functions that have implementation defined behaviour
when the requested size is zero
* many bug fixes, see https://valgrind.org/docs/manual/dist.news.html
- remove 32bit support for ALP
- add VEX-x86-pinsrd.patch (bko#276780)
- remove buildrequires on 32bit packages
- update filelist for 32bit disabled projects
* More DWARF5 support as generated by clang14.
- drop unnecessary procps buildrequires
- add upstream handle-rseq-syscall.patch to fix run with glibc 2.35
* 3.18.1 fixes a number of bugs and adds support for glibc-2.34, and for new
platforms x86/FreeBSD and amd64/FreeBSD. Debuginfo reading is faster, and
completed, and some newer ARM64 and S390 instructions are also supported.
- add s390x-z14-vector-support.patch (bsc#1180511)
