Yes, windows ;/ Seems that thread has some answers! Maybe bug him 
enough to fix the bug?

How far did you get with it?

"The problem seems to only manifest when a proper DllMain() 
method is exported from the library.  If none is provided, or if 
the given implementation can be optimized away, the error does 
not ocurr."

Was that the case for you too? That could be overcome with just 
using a normal function that is called right after loading?

I'm curious how the exporting of code as that seems to be the 
biggest challenge(so that we don't have to hand write the exports 
ourselves).


Thanks.
