But the language defines that the types in question must be 64-bit aligned, so it is legal for the compiler to emit this code. It's not a GCC bug. If you want to let the compiler know that a pointer to a type might not be aligned, you have to tell it so. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
