Package: libhunspell-dev Version: 1.4.1 The upgrade of libhunspell-dev to the 1.4 branch changed the API for get_wordchars_utf16:
const std::vector<w_char>& get_wordchars_utf16() const; However 'man 3 husnpell' still lists the old API: unsigned short * get_wordchars_utf16(int *" len) The API change was not advertised elsewhere either. It is not clear if the change was intended, but it breaks anything that uses this function. Upstream issue: https://github.com/hunspell/hunspell/issues/387
