You should direct this question to your Sun Studio support provider. This is an OpenSolaris list, and it appears from your description that you are compiling something which is not an OpenSolaris component. If that's not the case, please be aware that -fast should NEVER be used to build any part of OpenSolaris (my personal opinion is that it should never be used at all). If you're looking for general debugging strategies, you'll want to look at what -fast is expanding to on your particular machine, then try removing each of those options one at a time until you find a combination that works correctly. Then you will want to file a bug with your service provider describing the option (or combination of options) which causes the failure. It is also possible that this combination of options is triggering bugs in your code rather than the compiler. -- Keith M Wesolowski "Sir, we're surrounded!"
