Bug#827703: libc6: misaligned accesses in res_query.c to fields in HEADER struct
Package: libc6
Version: 2.22-11+b3
Severity: normal
Dear Maintainer,
We see various misaligned accesses reported on the console and in the syslog
running apt-get on hppa:
http(13559): unaligned access to 0x00000000fa703d49 at ip=0x00000000f9f0a9bb
handle_unaligned: 37 callbacks suppressed
http(13810): unaligned access to 0x00000000fa703d49 at ip=0x00000000f9f0a9bb

http(13810): unaligned access to 0x00000000fa703d4d at ip=0x00000000f9f0c69b
This is upstream BZ 20243:
https://sourceware.org/bugzilla/show_bug.cgi?id=20243
A patch has been submitted here:
https://sourceware.org/ml/libc-alpha/2016-06/msg00679.html
It resolves the unaligned accesses without affecting the public headers
which expose the HEADER typedef.
Please add to the 2.22 patch set if okay.
Thanks,
Dave Anglin
