Re: [Boost-users] 1.33 pointer to object serialization

Tell me a little more about this.

I presume that you've figured out what you want to do now.  How did you come
to a solution to your problem?  Did the STATIC_ASSERT indicate some flawed
code? or not?  Did the information make sense.  Note that I'm adding a short
explanation of this situation to the manual regarding this.  But the
existence of the STATIC_ASSERT is still a source of disagreement.
