I have not seen this test fail before. Bruno, I noticed you had written that self-test, could you add some printf's at various places (or single step it in gdb) to find out where it fails? Meanwhile I'll disable this self-test in libidn since libidn never uses O_BINARY or SET_BINARY and I can't find any gnulib code except for other self-tests that uses it either. (Which begs the question why the binary-io module is added at all? But that is a separate issue...) /Simon
