But it would be /very/ helpful if you could reproduce this and submit a bug report to LispWorks support. As you'll know they're currently working on the 5.0 release which will have some changes in the threading code as well. It'd be nice if they could fix that before they release the new version. Thanks again, Edi.

I've updated both the Lisp and the C++ code according to your recommendations - see ChangeLogs below. However, I'm a bit in a hurry and I couldn't figure out an easy example which shows that ReleaseDelegateAdapter is actually called - at least not from a DLL-based LWW image. Could you please check if it works and report back to the list if possible? Thanks a lot, Edi.

by Edi Weitz 22 Dec '04

22 Dec '04

No need to download this one because it doesn't contain any new or changed code compared to 0.4.0 - it's just that my laptop is alive and well again and I could re-sync with my CVS tree. Anyway, here's the Changelog: Version 0.4.1 2004-12-22 Some cleanup in docs All text files now have DOS line endings [Re-sync with my CVS tree (laptop was broken while 0.4.0 was released)] Download: <http://weitz.de/files/RDNZL.tar.gz> Happy Holidays, Edi.
