Well, I can't duplicate the problem.  I am using cfront 2.0 on a Sun and
all seems to work fine but I did have to make the following changes to
the code:

       I used fabs() rather than abs()
       I called strtod as follows:

               temp = strtod(argv[1], NULL)  /*ANSI definition*/ your
results was impossible.  If that's all you are missing, I would be
dissappointed that the compiler didn't generate an error.
This is the sort of thing that would cause the described flakey 
behavior.
