Re: [Boost-users] Serialization segfaulting

It would be interesting to know what compiler you are using.

In order to help we need a smaller piece of code that fails.

We have found and corrected on error in the 1.33.1 release candidate that 
might account for this.  You could check that by trying the RC_1_33_0 
branch.
