Using posix_memalign/std::align_alloc and then std::free results in the memory leak detector claiming "Deallocating non-allocated memory" #1853

Allocate some memory with posix_memalign (or the C++ std::aligned_alloc) & then try to free it since free is defined as the corresponding dealloc to pointers returned by posix_memalign. The memory leak detector fails claiming the pointer deallocatino is Deallocating non-allocated memory because posix_memalign isn't intercepted by cpputest..
