Wearing my Valgrind developer hat

https://github.com/google/sanitizers/wiki/AddressSanitizerComparisonOfMemoryTools

TILEGX has bee removed from Valgrind
FreeBSD support has been added to Valgrind
"Stack OOB" memcheck will detect errors, but only when the pointer is way out (like below the bottom of the stack).
As far as I know ASAN does not check syscall arguments, memcheck does.

There are also lots of other things that most tools detect

str* and mem* overlaps
invalid alignment
mismatched allocator/deallocator
mismatched alignment
mismatched sized deallocation
