Re: Still problem bootstrapping 3.0

[Andrew Pinski <pinskia at physics dot uc dot edu>]

It seems to be in memset (bah, 0, sizeof(*bah)); that is blowing it up.
the work around I found is by using bzero, which caused it compile,
but I don't know what the true fix is.

I would say it is in the builtin function for memset, but I don't know.

Thanks,
Andrew Pinski
