/* This test checks that the behaviour of iconv() in the situation of an
   invalid multibyte character after a shift sequence is consistent whether
   the entire buffer is passed at once, or whether it is passed in two
   subsequent calls.  Based on a bug report from
   Roman Rybalko <roman_rybalko@users.sourceforge.net>
   at <http://savannah.gnu.org/bugs/?24216>.  */
