- I FTPd the "paranoia" math testing program from research.att.com and gave
- it try on my OS/2 2.0 machine. I have both Microsoft FORTRAN 5.1 and
- WATCOM F77/386 9.01b (that is, the B-level patches have been applied).
-
- First of all, neither the double nor single precision version crashes
- OS/2, regardless of which compiler was used. I wonder why others have
- experienced crashes.
-
- Second, WATCOM passes with flying colors on the double precision test.
- On the single precision test, as well as both precisions with the Microsoft
- compiler, the program is unable to properly determine the radix, so the
- slew of defect messages that follow are presumably consequences of this.
- It looks to me like the program is fooled into thinking there are more
- significant digits than there really are, because of the wrong radix, so
- many of the defect messages seem to be triggered by inappropriate
- comparisons.
-
- Third, I didn't try either compiler with optimization disabled.
