package:devel/valgrind-devel[] is in the process of being updated.
This contains most of what will be in the official release of Valgrind 3.22 due out in October.

`memcheck` has been enhanced with some more checks.
It will now report usage of `realloc` with a size of zero.
Such usage is not portable and is deprecated (C23 will make it Undefined Behaviour).
`memcheck` now validates the values used for alignment and sized delete for `memalign`, `posix_memalign`, `aligned_alloc` and all aligned and sized overloads of `operator new` and `operator delete`.
Reading `DWARF` debuginfo is now done in a lazy manner which can improve performance.

As usual there are numerous small bugfixes.

Specific to FreeBSD there is now support for FreeBSD 15.
Two extra `_umtx_op` operations are now supported, `UMTX_OP_GET_MIN_TIMEOUT` and `UMTX_OP_SET_MIN_TIMEOUT`.
There is a fix for the use of sysctl kern proc pathname with the guest pid or -1, which previously returned the path of the Valgrind host.
The sysctl will now return the path of the guest.
Support for the `close_range` system call has been added.
