We are trying to upgrade from boost 1.31 (+ compaitable serialization) to boost v1.33. We have one particular test that is failing with what looks like serialization deserialing a bad pointer. In particular the bad pointer is the 3rd instance reference of a particular object. The 1st & 2nd deserialize fine the 3rd is bogus. This is code that works fine on 1.31 both binary & text mode. It works in 1.33 text mode, but fails in 1.33 binary mode. What is the best way to debug this problem? Is there anyway to inspect the binary archive to printout the contents...at least the pointers/addresses contained in the archive? I haven't been able to get it down to a simple test case (it is part of a large system). I could send out the binary and text archive if that would help. This is using g++ 3.3.4 on FC3 (32bit) & Also 3.3.4 on Red Hat Enterprise v3 on a 64bit platform. Keith mcneill@streambase.com
