Comment (by anonymous):

 Yeah I can now tell this issue persists in 1.56...
 Also I found a bug in my code. The issue was that I had two shared_ptr of
 which one was using a weak_ptr to the other. Then the one the weak_ptr
 pointed to got release by C++ before the other, so that the race condition
 above happened. I still think this should be fixed, because its obviously
 a race condition in boost too.

 I solved the issue on my end by simply turning the weak_ptr into a
 shared_ptr and the original shared_ptr that the weak_ptr pointed to into a
 weak_ptr. This will force the correct release order at application exit
 upon boost and prevents the race condition from happening.
