Hello,

> Logged by: Alexander Lakhin

> It looks that the following condition in NISortAffixes(IspellDict *Conf)

Yes, you are right. The second condition isn't right. Instead of
"ptr->issuffix != (ptr - 1)->issuffix" "Affix->type" should be checked
because we check for uniqueness of affixes.
The patch is attached.
