This was fixed for 4.5 by r152203:
http://gcc.gnu.org/ml/gcc-patches/2009-09/msg01869.html
http://gcc.gnu.org/ml/gcc-cvs/2009-09/msg00954.html

Backporting that to 4.4.6 fixes the test case there too with no testsuite
regressions (at least for me on i686-linux).

It's my understanding that upstream gcc 4.4 branch will be EOL:d soon, so you
probably have to apply that fix locally if you're not able to upgrade to gcc
4.5 or newer.
