Why do not program allocate neaded memory automaticaly? Do i need to calculate how much memory need to program and set its size before compilation always?

No. Are you sure it hangs ? My guess is that it is simply working very
hard. It only allocates a 1K buffer to load the file, so that should not
be the issue.
