Hi
This morning I recompiled the latest from GIT.
I noticed FGFS crashes when I exit the program. It appears the
AI-manager is trying to free buffers...
Here is the stack trace:
Program terminated with signal 6, Aborted.

I cannot reproduce this reliably, but it has occurred three times out of 10.
Has anybody been working on the AI-manager lately?
