I just installed Sun FORTRAN v 1.3.1 on my Sparcstation (SunOS4.1) and began reading the notes when I discovered: Complex arithmetic with -fast fails. If you specify inlining and a floating point option other than -fsoft, then complex arithetic fails. Example 1: f77 -fast any.f Example 2: f77 -cg89 -libmil any.f Well this is not a minor bug. I have a couple of questions though... 1. On my SS1, I can't invoke -fsoft as an option. It doesn't recognise it. f77 -help does not list it. Is this the default?? 2. Does anyone have some code that produces any errors (specifically in Ex. 2 as that is how I compile my code)? I have not noticed any gross errors in the output, but I wonder about the subtle ones that might bite me later. This really stinks! If you compile without -libmil everything takes *twice* as long to run. I really need some confirmation about the existence of this bug.... Thanks all, Robert | Robert L.

I reported this bug to Sun Hotline. Here is the reply I got from them. *** X-Subject: RE: SO#542715 - problems with complex in Fortran I am following up on a call that you were working on with Eric. Eric has asked me to look into this problem. You are right, there is a bug here in the inline math libraries. I have filed a bug against the Fortran compiler(bug#1043400) and we will get it fixed in a future release. Thank you for the information, this really does help us in fixing up our products.
