That seems not to be the problem. I have modified the loop like this:

for (int i=0 ; i < 10000 ; ++i) {
   Magick::Image image;
   Magick::Blob blob(data.c_str(), data.size());
   image.magick("SVG");
   image.read(blob);
   image.attribute("[MVG]","");
}

So I reset the MVG Attribute, which should already make no difference in 
that case, because the Image is contructed/destructed each time. But 
memory is still growing.

That's also the case in my original szenario: I have a simple COM 
object, which only loads XML data from a string and saves the generated 
image to disc. Using this object in a web page generating lots of images 
has caused the memory consumption of the IIS to explode.

Let me know if I can help to track down the problem.

Achim
