It was a bug in the test program, now fixed:

http://git.savannah.gnu.org/cgit/libidn.git/commit/?id=056262294467f3eaa96caf63c9573957b61301a9

However this won't make the self test pass, it just fixes the crash.

Maybe -- iconv returns NULL here.

Possibly libidn doesn't understand the locale it is in.  Can you run
'tests/tst_toutf -v' and post the output?
