From Marco Jez, "Problems fixed:

Browse Source 
1. type converters created automatically by the I_BaseType macro use
static_cast<> even for base-to-derived conversions. dynamic_cast<> should be
used instead.
2. as a consequence of the above fix, I_BaseType must now differentiate
between polymorphic and non-polymorphic base classes, because the latter
can't be dynamic_cast'd to derived classes. Some template magic (see
is_polymorphic<> in ReflectionMacros) is used to detect polymorphism at
compile time (I'm NOT sure it works on all platforms as it's partly
implementation-dependent. Please test!).
3. predefined custom property getters/setters/counters/etc. (as those
defined for STL containers) only work on Value objects that contain
non-pointer instances. This was an unwanted restriction that no longer
exists.

Wrappers will need to be recompiled. This is a good time to give them a
fresh update with genwrapper.

NOTE: fix #1 should get rid of those crashes and strange behaviours that
some users noticed while using osgIntrospection through osgTcl or in their
own code."
