Jean-Sebastian,

By an odd coincidence I'm currently looking at a list iterator bug in SDO
that is exposed when I build against the stdcxx library rather than the
standard Microsoft one. Is thsi issue urgent? If possible I'd like to
re-visit your case after I've resolved the stdcxx one (hopefully later
today) By then I might understand it all :-)

Geoff,

Here's the Exception and call stack I'm getting from sdo_test on
Windows, built with VC++ Express 2005:

     msvcp80d.dll!104f9961()

The exception is raised in list.cpp - line 309:
#if _HAS_ITERATOR_DEBUGGING
        void _Compat(const _Myt_iter& _Right) const
            {    // test for compatible iterator pair
            if (this->_Mycont == 0 || this->_Mycont != _Right._Mycont)
                {
                _DEBUG_ERROR("list iterators incompatible"); <---- There
                _SCL_SECURE_TRAITS_INVALID_ARGUMENT;
                }
            }

This is called from DataObjectImpl::~DataObjectImpl():
         PropertyValueMap::iterator i = PropertyValues.begin();
        while (i != PropertyValues.end())
        {
            unset((*i).first);
            if (i == PropertyValues.begin())  <-- There
            {
                // unset has not removed the item from the list - do it
                // here instead
                PropertyValues.erase(i);
            }
            i = PropertyValues.begin();
        }

And I am a little puzzled by the code in the above loop... Although I
didn't spend much time trying to grasp the logic here, and I have not
been playing with C++ iterators too much lately, my experience is that
removing entries from a collection that you're iterating on is usually a
sure way to shoot yourself in the foot :) so I may be wrong but I sense
a bug somewhere in this loop...

Could you please take a look and see if there's a quick fix for this?
Thanks.
