Back in the days when I was using the DigtalMars C++ compiler on almost a daily basis I always setted CPU affinity on HT/multicore machines for optlink.exe to avoid lockups.

I'm not aware whether or not there have been any fixes or changes to optlink.exe over the past 8 years regarding this issue.
