It's a very strange issue, but we need to definitely fix this issue
applyging a patch similar to Gav's, maybe using Peter Dimov's "yield_k"
( function.
I've been very busy lately to work in Boost and the little time I had
has been spent on Intrusive and Container.

I'll try to fix the issue in the following weeks, thanks for the ticket
and for testing Gav's patch.
