------- Comment #9 from et at ihear dot com 2005-11-15 22:10 -------
This cripples virtual inheritance for fine-grain parallel processing. There
should at least be a compiler option for process-independent referencing,
because admittedly, this would slow down dereferencing. Or maybe a operator new
placement variant that specifies process-independent referencing. I can see
that either way, it would cause major ripple effects. Maybe that's why I don't
see any action on this item since May.
I am making this comment because I think it is a very important enhancement to
make as soon as possible, as processors go multi-core. I have also read that
the other signicifant c++ compiler uses process independent referencing.
