This is similar to line 11 of the file "someheader.h":
class Class1: public Class2, virtual public Class 3 {

Sorry for not providing the source code. :(
I cannot do that because of my job contract.
If you wish, you can send some common quetions to me.

State-Changed-Why:
    without source, we cannot do anything. If you can
    produce a stripped down test case that'd be great.
    I'd really like a test case, as you've managed to trigger
    an assertion - something other bug reports about this have
    failed to do.
    
    N.B. what is important for this bug is the class heirarchy
    not the member functions and not the members (so long
    as there is at least one virtual fn for those that had
    virtuals, and at least one data member for those that
    were not empty)
