And it works, so the problem is not in the RTL itself, but in the

Correct - my test just shows there's a problem with write in multithread
env - the other runtime calls work. Also, my test doesn't replicate the
original DLL problem of this mail thread, that must be another reason
(missing IsMultiThread, missing /MT etc.)
Anyway, I really learned much more about multi-threading issues here and
will make all this information available on a Wiki page ('FPC
multithreading pitfalls') soon.
