Is it in a multi-threaded situation?

It may be this issue:
https://svn.boost.org/trac/boost/ticket/2713

See the fix here:
https://svn.boost.org/trac/boost/changeset/51103

We've ran into this issue recently as well when upgrading to 1.39 from
1.34  (perhaps we didn't notice it before though).  I hope to see this fix in an
upcoming release.

HTH,
