I think we can help you eventually, but:

1. Please post to the appropriate list:
   http://www.boost.org/more/mailing_lists.htm#cplussig

2. Please reduce your code to a *minimal* example that fails.  I'm
   sure you'll find your error that way, but if perchance you don't,
   at least we'll stand a chance of figuring out the problem.

3. Please post your example as an attachment so that line wrapping
   doesn't make it syntactically invalid.

Thanks,
