without my crummy debug statements the location of the crash in
comphelper/source/property/opropertybag.cxx is shown below


 510  // there's a property requested which we do not know
 511  if ( m_bAutoAddProperties )
 512  {
 513      // add the property
 514      sal_Int16 nAttributes = PropertyAttribute::BOUND |
PropertyAttribute::REMOVEABLE | PropertyAttribute::MAYBEDEFAULT;
 515      addProperty( *pName, nAttributes, pProperty->Value );
 516      // rPropInfo is invalid, refetch
 517      rPropInfo = getInfoHelper();
*518      *pHandle = rPropInfo.getHandleByName( *pName );
 519      continue;
 520   }

The valgrind log seems to indicate that the rPropInfo returned from
getInfoHelper has been deleted e.g.



==8524== Invalid read of size 8
==8524==    at 0x6CD2BF0:
comphelper::OPropertyBag::impl_setPropertyValues_throw(com::sun::star::uno::Sequence<com::sun::star::beans::PropertyValue>
const&) (opropertybag.cxx:528)

[...]

==8524==  Address 0x17dc66f0 is 0 bytes inside a block of size 32 free'd

==8524==    by 0x6CD2320: comphelper::OPropertyBag::addProperty(rtl::OUString
const&, short, com::sun::star::uno::Any const&) (opropertybag.cxx:368) 


but this ( afaics ) doesn't tally with the debug output I get :-/ which seems
to indicate we never access 0x17dc66f0 at ( opropertybag.cxx:528 ) I have to
admit I don't get it :-/// something strange is happening here or I am missing
something obvious
