It seems you do not have to add --fdm=yasim with this a/c? Is this
correct? I have not been doing this... when I tried --fdm=jsb
fgfs just aborts immediately, so assume adding the fdm is not
needed...
Anyway, on the 108, and yes, segfault after about 5 minutes... This is
with a fresh checkout of yesterday - OSG, PLIB, SG FG, and full
recompile...
Yesterday, did a quick 'flight' in the UFO --fdm=ufo --aircraft=ufo,
but at IAS of 500-1000 on 98 - no 'CRASH' - I figure when I reach flying
over/crossing the St Lawrence waterway I am safe ;=)) and I returned
on the reverse track...
And yesterday also did one flight in CitationX, but that was
in my WIN32 Vista source of about a week ago and again reached
the waterway without incident... but was using FGRUN, and had
a lot of other options like --atlas=socket,out,5,<MY IP>,udp,
no AI, no 'fog', and was a little higher, about 3,500 feet,
etc...
Also my WIN32 code has some protective code I _HAD_ to add
that does not allow triangles( int i1, int i2 ), and other shapes,
to be added if out of range of the _vertices.size()... windows
<vector> does a range check, and aborts the application if
out of range... maybe Mathias is addressing this... there are
lots of ongoing fast cvs changes in this area ;=))

I landed at CSS3, Montreal Les Cedres (I think) - boy I like a
plane that babbles at you - 'bank angle', when you turn too hard,
'1000 and 500 feet' when landing, etc - you feel like talking back,
and saying 'thank you'!
Will try adding my 'protective' code, very much needed for WIN32,
without the _MSC_VER switch, and see what happens... by adding
some printf() I checked and 'know' there are some calls to AddLine()
and addTriangle() at least, which are out of range... and this
is certainly some 'new' code.
Some questions:
1. Meantime could someone help me how to run gdb with fgfs... I
assume it is something like -
~/fg$ gdb --args ./fgfs --fg-root=... etc etc
(gdb) run
but after you see output of say -
count=160000

OpenAL error (AL_INVALID_VALUE): set_volume

}

MK_VIII::TCFHandler::update_runway (this=0x9a5a378) at mk_viii.cxx:4525
4525 runway.center.latitude = _runway->latitude();
(gdb)
what good things can I look at?
Note I have adjusted my CullVisitor limiter code to each 1000!
2. How set the autopilot to fly this 108 radial at 2500, say 250 IAS?
I have found the main [AP] switch, but where do I set the track,
altitude, speed, etc ??? Is there a dialog? Or how?
Regards,
Geoff.
