Re: [Boost-users] [serialization][1.33.0?] xml_iarchive leak

12 Aug 2005


      Hmm - this would surprise me.  It looks to me that maybe I'm missing 
something about clean up from exceptions.  baybe the std::ifstream lIn( 
lpszPathName ); should be moved outside the try block.  I wouldn't think 
that should be necessary but now that I look at this it might be.  What 
happens when you do this?  Any C++ expert want to opine on this?

Robert,
The following code leads to numerous leaks when lIn's contents are
not an xml_archive. Any thoughts on the cause?
try
{
   std::ifstream lIn( lpszPathName );
if( lIn.good() )
   {
           boost::archive::xml_iarchive ia( lIn );
   }
}
catch( boost::archive::xml_archive_exception& aExc )
{
   std::string lErr = aExc.what();
}
Thanks,
Jeff Flinn
