  No idea except in that function it's the library which allocates the 
output, and if you have allocator or binding problems that could very well
show up at that point.
  Try to use xmlSaveToBuffer and then copy the buffer content, that 
should garantee that memory allocation don't cross boundaries between 
languages and toolkits.
