Just 4 clarification:

basically I mean, that static/globally declared Objects in different
translation units are not effecitively instantiated before main(), and
that
I interpret the standard in a way, that those are guaranteed to be
instantiated, but not in a defined order. But in 3.0.4 the are not
instantiated at all.

So I guess that this problem could be reproduced by having 2 sourcefiles
wher

File A has:

namespace {
    MyClass A;
}
-------------
and File B has
namespace {
    MyClass B;
}
---------------
and File C has

main()
{
    Do_something();    // function which needs the side effects of
                        // A's and B's construction
}

example could be that the constructor of MyClass would set a global
string
to a certain value, and Do_something() depends upon this value to be
properly setup before main() gets control. And it's not feasible to
call/instantiate A or B locally.

I don't know if it matters that MyClass is actually a template.
