stream_fill_buffer does not set eof, only stream_read_internal does.
stream_read_internal should only be called when the stream
buffer is empty, and will only set eof if it cannot read any further
data, i.e. the current position really is the end of the file.
So something is wrong with your explanation.
One potential issue is that seeking back from EOF will not unset
EOF, that needs to be done separately, so maybe that is what
causes the issue you see?
