Status summary:
0) I merged in Jester's nan-fixes. That was easy:
git remote add -t nan-fixes jester
git://gitorious.org/~jester/fg/jesters-clone.git
git pull jester
make
I have not explicitly disabled real-weather-fetch, but
it appears to be non-enabled by default.
The ai-traffic remains enabled. This is the default.
So here's what I observe in this state:
1) If I want to get anything done, I cannot --enable-fpe
because that leads to an early FP exception, while the
splash screen is still up.
I cannot say whether this is due to intrinsic badness
in the fglrx driver, or whether the driver is being
passed unwholesome data.
#include <tirade about non-open-source drivers>
2) It is still easy to get SEGVs or ABORTs (due to
corrupt double-linked lists) when exiting from the
sim. Some logs including tracebacks are here
http://www.av8n.com/fly/fgfs//corrupt--21540.log
http://www.av8n.com/fly/fgfs//corrupt--21628.log
This appears to be about 90% reproducible chez moi.
It is at least as likely to happen after after a
short (30 second) simulator run as after a long
(90 minute) one.
3) The good part is that I can now sit stationary on
the ground, taxi, and even fly without seeing nan
messages spewed on the console. This is a major
improvement.
I attribute this improvement to Jester's patches,
since AFACT that is the only significant thing that
has changed since a couple of days ago.
Some seriously laborious debugging must have gone
into preparing those patches. It is much appreciated.
I am particularly amused by commit a3d5fda6b09e from
24 Oct 2009. It replaced 17 lines with 1 line and
produced a better result.
