That's funny, I've spent the better part of today trying to track a similar issue down. My scenario doesn't involve date_time, however. It uses tokenizer directly (which is getting used indirectly in your case by date_time). But my scenario is complicated, and my efforts to find a simplier repro have failed. Not a problem in date_time, but certainly a problem either in tokenizer or iterator (or possibly a compiler bug). I'm continuing to investigate. -- Eric Niebler Boost Consulting www.boost-consulting.com
