This probably depends on the amount of RAM you have, you have to take into consideration that each vector takes 3.2 GB (around 400 million samples * 8 bytes for each double value)!

The bug doesn't depend on the thread flag, something goes wrong
while searching for rows which is single threaded.
ATM I looking at it.

BTW, while seeing "all rows in the file have equal length"
the scanning for rows could be much faster, and I mean faster:
instead of minutes just a microseconds, files size divided by rowlength.
