Unifying the heap is known to be necessary to successfully pass string 
parameters between the main program and the library. Supposedly also 
Objects "free" and open arrays will not work as expected.

I once did that with Delphi (pre XE). It was easy.

But I have no idea how this is done with the fpc heap manager (though I 
seem to remember having read about it some time ago).

Of course as it needs to work in multiple OSes with different dynamic 
library paradigms, it's more complicated than in pure Windows Delphi.
