 In your comment, you said that you were using -O1. But after looked at the  
 error log and looks like you are using -O. Anyway, looks like it's GCC  
 bug? You can try the patch over at  
 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34215 .. If it fixes for you  
 then I can ask kan@ or/and someone to see if they can commit fix for GCC.  
 Don't know if patch is GPLv3 or not.
 
 Cheers,
 Mezz
