Is it possible to acknowledge that the current RTLs assumption is wrong
and it has to deal with threads during the System initialization?
(Because obviously the assumption is wrong, otherwise there was no crash.)
I think the assumption is definitely correct:
some subsystems needs to be initialized.
Since there are multiple systems to initialize, there will always be moments
in code where one system is initialized and the other is not
All code should be prepared to deal with that.
This counts double for systems where initialization is delegated to other
units: strings/threads on unix, for example
If you can prepare a simple sample program that shows the problem, I can try
to look into it. Maybe a fresh pair of eyes sees more than one pair of eyes?
