---------------
luabind (1.1.1-1ubuntu1) stonking; urgency=medium
* d/p/fix-object_rep-alignment.patch: cherry-pick fix from the Oberon00
luabind fork so object_rep's instance buffer doesn't claim more
alignment than lua_newuserdata() provides. With LTO, GCC used aligned
SSE stores on the misaligned userdata, making 21 tests segfault on
amd64. (LP: #2170791)
