Hi
I updated this morning, two hours ago, and I am still getting crashes on
exit. See the stacktrace below (AI is in lines 22 and 23).
Could this be some kind of race condition?
I should perhaps mention I have the mulithread property set in
preferences.xml:
<multithreading-mode>AutomaticSelection</multithreading-mode>
Program terminated with signal 6, Aborted.

However, I'm not sure it would ever have caused the kind of crash you reported.
Please update, and keep an eye for the crash - if you get them, post the
backtrace. naturally if anyone else sees a similar crash on shutdown,
mentioning the AI manager, please speak up.
(I'd love to see a valgrind run of the relevant code, but I suspect it will be
painful to generate the data, if the crash is intermittent)
