Greg,
This fix and my follow up don't seem to fix the problem that some other code
depends on the global static struct is writable.
Can you take a look at this?
The crash Sander reported is that Visual C++ put the static const structure
in a read only memory segment; the other compilers/OSs seem to allow writing
to it. I don't think marking the structure non-const is a real solution, as
this will give multithreading issues.
Thanks,
Bert
