[Boost-users] 1.33 pointer to object serialization

Hi,

I'm having trouble with serializing an object through a pointer to it.

The code below works in 1.32, but in 1.33 it gives the errors below.  I 
am using Mac OS X 10.4.2, gcc 4.0.

I've had a look at the headers, but my template programming isn't good 
enough to make too much sense of them.  It seems that there is a check 
to ensure T is not a pointer on line 549 of oserializer.hpp, which is 
the reason the static assert is failing?

Is it correct that objects shouldn't be serializable by pointers to 
them, or not?

Cheers
Chris
