Our named will core dump occasionally, and I'm not sure why.
Has anyone else out there seen something similar?

I've narrowed it down to that part of ns_resp after the long block
comment that starts "Penalize those who had earlier chances but
failed..."  The code is doing floating point computations involving
ALPHA, BETA, and GAMMA.  This makes me suspect that one of the
computations is overflowing.  Adb indicates that core was dumped while
processing "mull     $1.2000000000000000e+00,f0".  Won't I get a
SIGFPE if that multiply overflows?  Sound familiar anyone?
