Just need to set some utf8 locales (I guess, tried and using 
en_US.UTF-8). It doesn't matter if the file exists.

The same here. NON-utf8 locale working. bash-4.1 working also with utf8.

bash-4.2 get stuck in xdupmbstowcs2() static function in do-while loop. 
I know nearly nothing about wide chars so I don't know what is bad here.
