The build error was from libc++. Specifically, libc++ calls `posix_memalign` when `new` is called. I noticed this in the functions included with `#include <memory>` (in `utils/testutils/StreamWrapper.cpp`, and possibly other test utils), but it probably effects most of libc++. As far as I'm aware your libc memory functions don't call malloc and work fine under the LLVM embedded toolchain, but I understand the confusion. I'll try to be more clear with my phrasing in future.
