Hmm well the KOI8 tests unsurprisingly produce random results on non-
KOI8 input. It's pure chance you didn't get EILSEQ.

What errno did you get for the C locale test? On which input character?
Perhaps it's sihnalljng EILSEQ for every byte >0x80 ? That seems
broken to me but perhaps not to a glibc pedant out there.
