FYI, I've had a similar problem with a daemon program dumping 1.9GByte core 
file after running for a day or two. After debugging for some days I found the 
cause: I forgot one call to xmlFreeDoc(). Although the XML document in 
question was short (only around 4Kb in text size), the in-memory tree 
representation was that big, that parsing this file up to 100 times led to a 
memory usage of 1.9GByte. So its not libxml2 leaking memory itself, but its 
the programmer making small mistakes, that leads to such fast memory leaks.
