Hi
Filling for tracking the upstream issue BZ#27256:
> Tavis Ormandy reported that when converting from ISO-2022-JP-3 to
> UTF-8, the gconv module could trigger an assertion failure in
> iconv/skeleton.c if the second wide character in a two-wide-character
> sequence cannot be written to the output buffer during character set
> conversion.
>
> If glibc is built with assertions, this assertion failure can
> typically be triggered by applications (such as mail clients) which
> use the glibc iconv subsystem for MIME character set processing.
Regards,
Salvatore
