byLine reuses a buffer (for speed) and the subsequent split
operation just returns slices into that buffer. So when byLine
progresses to the next line the strings (slices) returned
previously now point into a buffer with different contents.
You should either use byLineCopy or .idup to create copies of
the relevant strings. If your use-case allows for streaming
and doesn't require having all the data present at once, you
could continue to use byLine and just be careful not to refer
to previous rows.
Thanks. It now works with byLineCopy()
