+The =library-loaded notification has 4 extra fields:
     symbols-loaded - indicates that there are symbols for the loaded library
     symbols-path   - if symbols are exist then it contains a path for symbols of the loaded library
     loaded_addr    - contains an address of the loaded library or "-" if address isn't resolved yet
+    size           - contains the size in bytes of the section loaded at 'loaded_addr'
