--- Comment #2 from Artem <tyoma.ariv at gmail dot com> ---
Thank you for help.
Could you please also advise which kind of optimization performed here. Could
it be switched off by using some compiler options? (because there are a lot of
such places in the source code)
Also I notice that such behavior reproduced only with NIN defined to values
from 2 to 4. If the value is grater such behavior is not reproduced.
