And what I was talking about? You get precision and don't lose speed while memory is not an issue to you if you move your stuff to double or extra precision and the problem is solved while the bug is investigated. I am also interested in solving all sorts if crashes and slowdowns associated with underflows. I pulled my hairs due to that for first time 20 years back with exp(-x) while x-->100. And 2 years back with multithreading. And as recent as a month ago. But in my recent case crash took place when I incorrectly used real4, real8 and real*10
Interesting if compile crashing code with Intel compiler and Clearwin. Does it crash? Can anyone with Intel IVF confirm? If not then why don't take Intel's solution, Paul? Is it possible to disassemble Intel's code? If underflows is design issue of FTN95 then default has to be changed to the one like in Intel, i.e. to ignore the underflows.
