[Boost-users] Crash when serializing binary object to XML archive

Subject: [Boost-users] Crash when serializing binary object to XML archive

Using Boost 1.36, I'm seeing a crash when serializing a 256K malloc  
block
using binary_object to an XML archive, something like this:

using namespace boost;

serialization::binary_object dataObject =
               serialization::make_binary_object(dataBlock, dataSize);
ar << serialization::make_nvp("data_contents", dataObject);

The crash is in
boost::archive::iterators::transform_width<char const*, 6, 8,  
char>::fill ()

template<class Base, int BitsOut, int BitsIn, class CharType>
CharType transform_width<Base, BitsOut, BitsIn, CharType>::fill(){
    CharType retval = 0;
    unsigned int missing_bits = BitsOut;
    for(;;){
        unsigned int bcount;
        if(! m_bufferfull){
            m_buffer = * this->base_reference();  <-------- crash here
            m_bufferfull = true;
            bcount = BitsIn;
        }
        else
            ...

and the stack back up to my object serialization looks like:

This is on Mac OS X, using gcc 4.0, compiling for intel.

Has anyone seen this crash? Should I reduce and file a bug?
