RFC 17: Dynamic Array Sizing

[Benedikt Rothe]

Hi 

Sorry for posting in this list since I'm no mapserver-developer, but I 
wonder wether RFC17 may break 
mapscript-applications, which hold pointers to mapserver-Objects.

Example Java:
- A Java-layerObj is created with "aMapObject.getlayer(1)". This 
layerObj-instance holds a pointer 
  into the Layer-Array of the aMapObject.
- After this, a new layer is added to the webobject.  The layers-Array in 
the webObject could be reallocated 
  by this action.
- Therfore the existing pointer in the Java-layerObj could become invalid.
This could cause crashes.

Did I oversee something?
