You are right, and the old code already resized the buffer for a non-zero size, so that part of my change isn't needed. What I changed is size zero: setvbuf(f, nullptr, _IOFBF, 0) left the stream with no buffer at all, so asking for a buffer to be provided silently turned buffering off

If you think that is the correct reading of the standard I will drop it and keep only the delete[] fix
