Either that, or the this-pointer is screwed.
(You shouldn't need to be doing a dynamic_cast there, a const_cast
should be enough. However, the dynamic_cast should nevertheless
succeed.) I suggest using the debugger and make sure the this-pointer
points to something meaningful, after you've enabled RTTI.

do you have run time type info enabled in your visual studio project?
If you don't than, I believe that's your problem.
Project properties -> C/C++ -> Language -> Enable Run-Time Type Info

Hi,
in the meantime I tried to extend ShadowMapViewport. I followed step
by step Dirk's post
(http://www.mail-archive.com/[email protected]/msg02309.html
<http://www.mail-archive.com/[email protected]/msg02309.html>)
creating a SoftShadowMapVieport class + base class which extends
ShadowMapVieport.
Everything compiles and builds well, but at runtime, during newPtr
call in shallowCopy method the program crashes with this error:
not handled exception 0x7c81eb33 in rthdriClient.exe: Microsoft C++
exception: __non_rtti_object @ 0x0012f830.
Code where crash happens:
FieldContainerPtr SoftShadowMapViewportBase::shallowCopy(void) const
{
SoftShadowMapViewportPtr returnValue;
here --->> newPtr(returnValue, dynamic_cast<const
SoftShadowMapViewport *>(this));
return returnValue;
}
The only change I made from the Dirk's check list was to remove the
fields already present in ShadowMapViewport; otherwise I get "WARNING:
ERROR: Double field description in ..."
