I just ran into this problem myself on a 24-core system running IDL 8.2.3 on 64 bit Linux. I can create 24 bridge objects and use them for processing, but if I destroy them in the same order they were created then IDL hangs after destroying the 8th one. If I destroy them in reverse order, everything works fine.

You replied that this is a known bug (CR64611), and that Tech Support had identified a possible workaround. However, the bug is still there in IDL 8.2.2 (linux 64-bit), a year later.
