Comment 1 Andrew Pinski 2011-12-16 01:14:46 UTC 
Confirmed, only fails on 4.4.x
Comment 2 Mikael Pettersson 2011-12-26 17:08:09 UTC 
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.
Comment 3 Jakub Jelinek 2012-03-13 13:04:40 UTC 
Fixed in 4.5+, 4.4 is no longer supported.
