Okay, managed to put in some debug

here the code snippet(s) were the debug was done ( same for 
distro/no-distro except for some text to distinguish one from the other )

ww8par3.cxx: ( SwWW8ImplReader::Read_F_FormCheckBox )
[...]
     if (aBookmarkName.Len()>0)
     {
         IDocumentMarkAccess* pMarksAccess = rDoc.getIDocumentMarkAccess( );
         //IFieldmark* pFieldmark = dynamic_cast<IFieldmark*>( 
pMarksAccess->makeNoTextFieldBookmark(
         IFieldmark* ptr = ( pMarksAccess->makeNoTextFieldBookmark(
                 *pPaM, aBookmarkName,
                 rtl::OUString::createFromAscii( ODF_FORMCHECKBOX ) ) );
         IFieldmark* pFieldmark = dynamic_cast<IFieldmark*>( ptr );
         OSL_ENSURE(pFieldmark!=NULL, "hmmm; why was the bookmark not 
created?");
         if (pFieldmark!=NULL) {
             IFieldmark::parameter_map_t* const pParameters = 
pFieldmark->GetParameters();
             ICheckboxFieldmark* pCheckboxFm = 
reinterpret_cast<ICheckboxFieldmark*>(pFieldmark);
             OSL_TRACE( "distro ( Read_F_FormCheckBox ) %p %p %s %p %p 
%s %p %p %s reinterpret %p %s\n",
                 ptr, dynamic_cast< void* >( ptr ), typeid( *ptr ).name(),
                 pFieldmark, dynamic_cast< void* >( pFieldmark ), 
typeid( *pFieldmark ).name(),
                 pCheckboxFm, dynamic_cast< void* >( pCheckboxFm ), 
typeid( *pCheckboxFm ).name(),
                 reinterpret_cast<ICheckboxFieldmark*>( ptr ), typeid( 
(*reinterpret_cast<ICheckboxFieldmark*>( ptr ))).name() );
             OSL_TRACE("dynamic_cast<ICheckboxFieldmark*>( ptr ) %p", 
dynamic_cast<ICheckboxFieldmark*>( ptr ));
[...]


docbm.cxx ( MarkManager::makeNoTextFieldBookmark )
[...]
         sw::mark::IMark* pMark = makeMark( rPaM, rName,
                 IDocumentMarkAccess::CHECKBOX_FIELDMARK );
         sw::mark::IFieldmark* pFieldMark = 
dynamic_cast<sw::mark::IFieldmark*>( pMark );
         sw::mark::ICheckboxFieldmark* pCBmark = 
dynamic_cast<sw::mark::ICheckboxFieldmark*>( pMark );
         OSL_TRACE( "distro (makeNoTextFieldBookmark ) %p %p %s  %p %p 
%s \n", pMark, dynamic_cast< void* >( pMark ), typeid( *pMark ).name(),
pCBmark, dynamic_cast< void* >( pCBmark ), typeid( *pCBmark ).name( )
[...]

and the results......

disto 32-bit
============
distro (makeNoTextFieldBookmark ) 0x8d013a4 0x8d01370 
N2sw4mark17CheckboxFieldmarkE  0x8d013a4 0x8d01370 
N2sw4mark17CheckboxFieldmarkE

(interesting in the library the implementation is in the dynamic_cast  
works )

distro 0x8d013a4 0x8d01370 N2sw4mark17CheckboxFieldmarkE 0x8d013a4 
0x8d01370 N2sw4mark17CheckboxFieldmarkE 0x8d013a4 0x8d01370 
N2sw4mark17CheckboxFieldmarkE reinterpret 0x8d013a4 
N2sw4mark17CheckboxFieldmarkE
dynamic_cast<ICheckboxFieldmark*>( ptr ) (nil)

( and here it doesn't so I guess there is some symbol confusion.. but I 
don't see it )

does anything here stand out? ( /me is not that up on library symbol 
binding, visibility etc. stuff.... must read more :-) )
