[libvirt] build issue due to '-Werror=cast-align' on ARM (armhf) [was: Re: [Xen-devel] [libvirt test] 63528: regressions - FAIL]

Hello, The Xen Project's automated test suite is failing at running its libvirt tests for a few time, like this: On Wed, 2015-11-04 at 09:04 +0000, osstest service owner wrote: More specifically (from a more recent run): CC util/libvirt_util_la-virnetdevmacvlan.lo util/virnetdev.c: In function 'virNetDevParseDadStatus': util/virnetdev.c:1319:188: error: cast increases required alignment of target type [-Werror=cast-align] util/virnetdev.c:1332:41: error: cast increases required alignment of target type [-Werror=cast-align] util/virnetdev.c:1334:92: error: cast increases required alignment of target type [-Werror=cast-align] cc1: all warnings being treated as errors make[3]: *** [util/libvirt_util_la-virnetdev.lo] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: Leaving directory `/home/osstest/build.64130.build-armhf-libvirt/libvirt/src' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/osstest/build.64130.build-armhf-libvirt/libvirt/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/osstest/build.64130.build-armhf-libvirt/libvirt' make: *** [all] Error 2 The changeset being tested last, as of now, and still failing, is: db92aee2b477355759351889e37a365379b43bf6 Full logs available at the following links: http://logs.test-lab.xenproject.org/osstest/logs/64130/build-armhf-libvir... http://logs.test-lab.xenproject.org/osstest/logs/64130/build-armhf-libvir... Right now, I don't have an ARM cross build environment handy to try to reproduce and attempt a fix, so I figured I at least was reporting it here.
