That explains a lot of things indeed. It doesn't explain why the
exception handling on Linux fails (that should still work fine even
with two separate copy of each typeinfo object, IMO), but it gives a
clue as to what things may have broken: you get two copies of each
global object, and gives you access to both copies. Depending on the
exact interaction sequence, it is well possible that all kinds of
corruption occur.
