--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Don't have a non-checking-enabled 4.4 handy but I can confirm this at -O0 with
using GCC 4.3.4 (12s) vs. 4.8.5 (161s) on x86_64-linux.

 expand                  : 133.99 (83%) usr   2.65 (47%) sys 136.34 (81%) wall 
 98925 kB ( 7%) ggc

I believe this was fixed at some point, GCC 4.9 is back to 14s here, so are
GCC 5 and 6.

Thus fixed (GCC 4.8 is no longer maintained).
