Created attachment 72993 [details, diff] simple solution
any one is gonna merge the fix to portage ? No ebuild update for >1y , thats getting long. Are maints still alive ?
Simply don't use such flags as -fforce-addr or -ffast-math in CFLAGS since they are known to cause breakage. We cant or wont start filtering all ricerflags..
