I think this has been fixed on the trunk by:
2011-11-08 Michael Matz <matz@suse.de>
...
* tree.h (TREE_CLOBBER_P): New macro.

Works with 4.5 and 4.6 because tree-ssa-sink.c is basically "broken" for
memory there (after alias improvements merge). That was fixed for 4.7
which was in turn broken again for this testcase which indeed was fixed
by Michas patch.
Thus, a 4.4. regression only now.

"Fixed" by dumber sinking in 4.5/4.6 and fixed for real in 4.7+. 4.4 is no
longer supported.
