Is your program (the code that uses shared_ptrs) running in multiple
threads?  I am seeing problems with my multithreaded code where the
use_count in the shared_ptrs is not accurate and causing all sorts of
problems.  I'm even seeing core dump backtraces showing problems in the
scoped_lock where the shared_ptr use_count is getting updated.  It appears
that there are a lot of restrictions on how shared_ptrs can be used in a
multithreaded program, and I may be breaking some of those restrictions as
it is easy to do so.  In any case, let me know if you find a solution to
your FIM errors.  I have a feeling I'm seeing symptoms of the same
problem.

Thanks.
