Hmm, the huge problem with this kind of errors is that you do mostly not see when the root of that problem happens. Enabling floating point traps in the cpu points often to a place where the problem has happened already. I have a patch for valgrind available that is waiting to be fed back to valgrind which /could/ help on that. But not yet done ... In the meantime: Is there a specific model that triggers this problem? Any chance?

lines 319-321 for desperate cases :

I've had tons of nans at startup of the bf109 and fw190. They stopped once the Aircraft gained some speed and the rest of the flight was fine. This started approximately at the time of the ambient update. My other machine ran both Aircraft fine so I didn't bother much. Todays I updated to 2.9.3 and all the startup nans were gone. > > -- > Stay on top of everything new and different, both inside and > around Java (TM) technology - register by April 22, and save > $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. > 300 plus technical and hands-on sessions.

Adding a test for NaN will prevent (or at least mask) the problem:
strength = lift_mps * SG_METER_TO_FEET ;
if(isnan(strength)) strength=0;
_ridge_lift_fps_node->setDoubleValue( strength );
We could add some debug printing, too perhaps:
strength = lift_mps * SG_METER_TO_FEET ;
if(isnan(strength)){
strength=0;
cout << /* whatever variables we need */ << endl;
}
_ridge_lift_fps_node->setDoubleValue( strength );

Jano, may I ask you to do a little experiment ?
As you have a machine which triggers the error, maybe you could try this:
comment out all the formulas, and replace them by a nice constant, all over
the file.
Then, from bottom to top, and one by one, put the original calculations back.
Maybe that could help focus on the one that produces the bad thing ?
Then, you could also try the following ?
line 231 : if (timer >= 1.0 ) {
this waits 1 second before doing a scan, maybe
* this could be raised to a longer time ?
* this could be replaced by something that tells us for sure the scenery is
here,the plane is placed, and that get_elevation_m is ready to work ?
I'm blind here for these experiments...

You might want to try to comment out line 66 of src/Main/bootstrap.cxx
in such case. It'll then throw an exception and a core dump which could
be analysed:
static void

fpu_control_t fpe_flags = 0;
_FPU_GETCW(fpe_flags);

// fpe_flags &= ~_FPU_MASK_UM; // underflow
// fpe_flags &= ~_FPU_MASK_PM; // precision (inexact result)
_FPU_SETCW(fpe_flags);
signal(SIGFPE, handleFPE);

We've occasionally seen lots of NaN's before addition of the ridge-lift as well and they had never been adresses substantially. I don't mean to blame anyone, instead I'd like to revive the idea that the ridge-lift is probably just triggering a long-standing 'feature' not that I claim to have the slightest clue which one it would be, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.

I've been seeing this every time I load on Ubuntu Hardy. I'm 90% sure that the ridge-lift enhancement is the root cause - it's the only source change that went in when I rebuilt last. I think they are generated by OpenSceneGraph, and later versions may suppress the messages. I'm away from my FG machine right now, but from memory I'm currently using OSG 2.7.X. I'm in the process of rebuilding to 2.8.1rc2 to see if that hides the messages. However, even if the messages are being hidden, I think it would be worth tracking down the root cause. -Stuart -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
