Hi Dimi, The build break might be caused by your commit for bug 916428, would you mind check this build break on flatfish? Thanks,

Hi Danny, Could you try delete objdir-gecko and rebuild again ? I have faced the same issue but it works after clean objdir-gecko

(In reply to Dimi Lee[:dimi][:dlee] from comment #2) > Hi Danny, > Could you try delete objdir-gecko and rebuild again ? > I have faced the same issue but it works after clean objdir-gecko It doesn't work, still build break. Please note flatfish is tablet without enable MOZ_B2G_RIL and it's ICS version with gcc 4.6.

Hi Danny, Could you help check if attached patch works ?

remove assignee until we decide to use this solution instead of changing gcc

This breaks generic flame-kk builds also when using gcc 4.8.x. We should really consider fixing this as the patch is straightforward and also fixes the issue under these circumstances.
