Thanks for reporting this.

Peter Dimov looked into this and found that the cause is recently added 
use of __forceinline.

A suitable workaround until the next Boost release is 
-DBOOST_CONTAINER_DISABLE_FORCEINLINE

I can't speak for Ion, but I'd assume it'll be fixed next Boost release.

Once again thanks for reporting this, it wasn't noticed by the usual 
release testing.
