The problem you seem to hit on Linux doesn't exist on windows, since
symbols from the static libraries are not public symbols (an equivalent
of hidden symbols is always switched on). This means that you can link a
static library into every binary you have, and still they cannot
interact there. This also marks the problem: you will not be able to
share memory between those binaries, which means that a memory region
allocated from the static library in A.dll cannot be freed by the static
library in B.dll. similar issues exist for other kinds of memory transfers.

regards,
Patrick
