It was noticed on big-endian systems that msgfmt would fail with the following error: msgfmt: gconv_builtin.c:70: __gconv_get_builtin_trans: Assertion `cnt < sizeof (map) / sizeof (map[0])' failed. Aborted (core dumped) This is only seen on installed systems because it was due to a corrupted gconv-modules.cache. iconvconfig had the following issues (it was specifically freeing fulldir that caused this issue, but other cleanups are also needed) that this patch fixes. - Add prefix only if dir starts with '/' - Use asprintf instead of mempcpy so that the directory string is NULL terminated - Make a copy of the directory reference in new_module so that fulldir can be freed within the same scope in handle_dir.
