This regression is most unfortunate because it penalizes languages
that use virtual function dispatch tables in const memory: AFAIK that
means C++ and Java at least.
The regression seems to have been introduced because of a double write
problem in C++ constructors.
Can one of you optimization gurus look at this one, please?
Andrew.
