For those who dont know what the PARANOIA program is:

This program is for checking FORTRAN compilers, although I believe
there is a C version as well. It "specializes" in testing precision
of various floating point operations as well as testing how the
compiler reacts to division by zero, overflow etc. Because of the
exceptions it generates, it is normal for the program to be aborted
several time during execution. It writes all its results in a log
file, so when it is rerun after aborting, it starts from the previous
point rather than the beginning.

You can get this program by FTP to
        netlib@research.att.com
 login as netlib (not anonymous!) and look in the directory 
paranoia for the files dpara.f (for double precision) and spara.f
(for single precision).

I ran the DPARA program compiled with MS-FORTRAN 5.0 under MS-DOS,
OS/2 Vers 2.0 & 1.3. Under both MS-DOS & 1.3 the program ended with
1 "flaw" - which is quite good grade. Under 2.0 it crashed the system after
Milestone 90, which tests powers of z^i for small integers z, i.
What's worse is that it is impossible to restart the program, because
CHKDSK must be run and it does something to the log file which 
prevents the program to restart from the previous abort. 


So, it looks like the problem is not just with division by 0, but
other arithemtic as well.

My machine is 386, with 387 Cyrix coprocessor.
