Hmmm. I was having a problem that I was starting to write up the night
before last, until I saw your post. I thought it was the same problem,
and you'd reported it. But now I'm beginning to wonder if they *were*
the same problem. I get the impression from the above that your segfaults
are occuring promptly, at the beginning of the scenario.
I'm getting segfaults that seem related to the AI subsystem. They occur
when I turn AI traffic on through the menu. They seem more frequent
as I turn the AI traffic density up from 1 to 3. But they don't occur
promptly upon start; instead, they almost always occur when I'm on final
for a landing. --log-level=debug shows no useful messages -- there's
just an abrupt end. But if I don't enable the AI traffic, I don't get
the segfaults.
