When asserting that g++ gives no warning or error, please test a recent g++:

Using MacPorts' gcc46 package:

$ g++-mp-4.6 -c dyncast8.C 
dyncast8.C: In function 'int main()':
dyncast8.C:14:19: error: uninitialized const 'b' [-fpermissive]
dyncast8.C:10:7: note: 'const class Derived' has no user-provided default
constructor
