This test case was fixed on trunk by r171465:
http://gcc.gnu.org/ml/gcc-patches/2011-03/msg01765.html
http://gcc.gnu.org/ml/gcc-cvs/2011-03/msg00889.html
However r171465 caused PR48290, so a backport also needs the two PR48290 fixes
(r171657 + r172494). With all three backported to 4.6.2 the test case is fixed
there too with no test suite regressions for me on i686-linux.
But this may be a too large change for the upstream 4.6 branch.
