// Generally its a bad idea to call I/O function from malloc
// if they call malloc we will end up with an infinite recursion.
// This file contains simple tracing functions which don't use malloc.
// You can use them instead of std::cerr or fprintf.
// This code is known to be incomplet and incorrekt and it lacks
// support of signed types.
