We got a similar bug with the option -feliminate-dwarf2-dups of gcc 4.5.1 when
building Qt in the embedded Yocto project:
http://bugzilla.pokylinux.org/show_bug.cgi?id=932

One difference is we are not in c++0x mode.

I tried the patch http://gcc.gnu.org/ml/gcc-patches/2011-01/msg01637.html, but
still got the same issue.
