Is that object being concurrently accessed from different threads? If
it is, is it thread-safe? If it's not, did you incor****ate any
synchronization primitives to make sure every thread has an exclusive
access to the object and it's not possible for several threads to
modify it at the same time or read it when it's in some intermediate
state (being modified by some other thread)?
I also think asking this question in the appropriate C++ group would
be helpful.
