It looks each dll has own gc.

If instance allocated in main program points instance allocated in dll
or vice velsa, whats happen?
as main GC, instance pointed from dll gc looks garbage, so it will freed.

One of the safety way is, sepalete gc (or whole phobos) as dll,
and both program and dll link it to use only one gc.

any suggestion?

not that long ago.  Check out:

In particular look at the section "D code calling D code in DLLs" to see
 the use of std.gc.setGCHandle(), std.gc.getGCHandle(), and
std.gc.endGCHandle() functions.
