That is, the only real solution to this problem is to convince the
Firebird folks to remove their atexit() calls from the client
libraries? I'll try, but I'm not very confident this is going to
work. Also, I'm wondering how other OSes handle this. I don't see this
code crash on Linux, contrary to its design as you say.
Thanks anyway to you, and to Jason Evans, for your replies.
Not sure but I'd guess that each library calls its at_exit entrypoints
as part of its unload handling.

Markus
