Thank you for looking into this.
RTLD_GLOBAL does not fix the incorrect dynamic_cast.
Also, there are situations where dlopen is used without
RTLD_GLOBAL for a good reason, and adding the RTLD_GLOBAL
flag sometimes just isn't possible.
I definitely prefer "correct" over "fast", especially
when the difference in performance is rather small, as
in this case.
