--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> 2010-12-07 21:40:38 UTC --- With current mainline 200000 elements finishes in 0.1s on my x86_64 system, which is only 5 times slower than non-debug mode. That's compared with 5m36s with 4.5's debug mode. I think it's safe to say François has fixed it :)
