Paranoia freaks under SVS Fortran!

In article <1991Mar1.194517.10627 at notvax.ccny.cuny.edu> I write:
[Failures in single precision PARANOIA]

> The number of DEFECTs discovered = 5
> The number of FLAWs discovered = 2
> The arithmetic diagnosed has unacceptable Serious Defects.
Well, I did the double precision and C versions, and you wouldn't believe
[Double precision PARANOIA]
The number of DEFECTs discovered = 4
The number of FLAWs discovered = 2
The arithmetic diagnosed may be Acceptable despite inconvenient Defects.
And from the C version:
The number of FAILUREs encountered = 1.
The number of SERIOUS DEFECTs discovered = 1.
The number of DEFECTs discovered = 3.
The number of FLAWs discovered = 2.
The arithmetic diagnosed has unacceptable Serious Defects.
Potentially fatal FAILURE may have spoiled this program's subsequent diagnoses.
I wonder just what's going on here. I haven't done the double-precision
fix to notvax; I'll run this again on my home machine that has been
fixed. All this might mean nothing, just that it's not correct to
have so much in the error department. For those who use floating
point math, beware!
