Further investigation confirmed this nice and helpful test failure. Following commit removed usage of ALIGN_BUFFER_OFFSET on entry to __read_etc_hosts_r(): http://git.uclibc.org/uClibc/commit/?id=f65e66078b9f4d2d7f0fc336dee36e78fc467c0f So indeed if target architecture doesn't allow unaligned access and provided tmp buffer is not word aligned (and we will deal with pointers which means word-sized data units), then CPU will fail during execution. In case of ARC we'll see "Unaligned access" exception like this: --->8--- # potentially unexpected fatal signal 7.
