Here is an article about the potential problems about passing CRT objects
across DLL boundaries:


In the context of the Erlang emulator, you could run into those problems if
you load drivers into a statically linked
emulator, as they would use a different copy of the run-time library.

As long as you don't load dynamic drivers, statically linking the run-time
library would be OK since there would
still only be one copy of the run-time library.
