That is because to my knowledge we does not have something like "crealloc" to grow allocated memory effectively. Naive implementation of such function will lead always to coping memory from old to new area and effective would far

True, but return type of free() is void, thus it says nothing about return value. The POSIX says: "If size is 0, either a null pointer or a unique pointer that can be successfully passed to free() shall be returned."

I see, but could you please provide better alternative? I couldn't find anything more alive and representative than Boehm GC.
