To me this sounds like a compiler bug.

I think your compiler has a bug using virtual inheritance.

Removing the 'virtual' before the dtor in o2be_name should not cause
any harm since its base class, AST_Decl, has virtual dtor and thus
all dtors in the derived class will be automatically declared as virtual.
I've tested that for egcs and vc++ 6.0.

I'm not that familliar with the code to say what will happen if you
remove the virtual inheritance though :-/
