This is the ci2_mem.h implementation. It's 'just wrappers for the general
stdlib allocators. If they fail they raise an exception with macro magic. All
other functions that may raise an exception are in include/platform/try. It's
not recommended to use these functions, as they are hard to debug and it's not
a robust way to handle errors.
