Thank you for the report.

For GNU libiconv, this has now been fixed:
http://git.savannah.gnu.org/gitweb/?p=libiconv.git;a=commit;h=0a04404c90d6a725b8b6bbcd65e10c5fcf5993e9

For GNU glibc (which contains the main GNU iconv implementation), a bug report
is still open: https://sourceware.org/bugzilla/show_bug.cgi?id=2373

Best regards,

                Bruno
