The Boost.Function thread-safety problem is NOT fixed in 1.34.1.  Quote:

   Boost.Function  in Boost 1.34.x has a bug  that affects the construction
   of Boost.Function objects in a multi-threaded context. The problem 
has been
   fixed in the Boost trunk and for the upcoming Boost 1.35.x.

So either you've got a different problem, or it is now masked.
