Because some other DLL that was loaded on process startup allocated
memory differently - in a different order, different size because or
something, or something like that.
I didn't mean race condition between backends. I meant against a
potential other thread started by a loaded DLL for initialization.
(Again, things like antivirus are known to do this, and we do see these
issues more often if AV is present for example)
