Hi,

I am using your example file with emacs -Q (Emacs 25) and had no problems,
flyspell-buffer works as expected after setting ispell-program-name to
hunspell and set ru_RU as dict (hunspell 1.6.2 here).

Local Ispell dictionary set to ru_RU
Starting new Ispell process hunspell with ru_RU dictionary...
Checking region...
Spell Checking...100% [laborum]
Spell Checking completed.

The auto-detected values for hunspell ru_RU are

(ru_RU [[:alpha:]] [^[:alpha:]]  t (-d ru_RU) nil utf-8)

Wonder why otherchars is not shown.

Seems I was wrong, it is a long time since I digged there.

¿What happens if you use "[[:alpha:]]" and "[^[:alpha:]]" instead if the
explicit character strings 
"[АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЬЫЪЭЮЯабвгдеёжзийклмнопрстуфхцчшщьыъэюя]"
and "[^АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЬЫЪЭЮЯабвгдеёжзийклмнопрстуфхцчшщьыъэюя]"?
