[Flightgear-devel] FG crashes when changing visibility
Hi, I was noticed that FG hangs and than crashes if pressing z key. If visibility value is not controlled by user, it can be occasionally **increased to a huge value (1000 km). In this case TileLoader is trying to load hundreds of tiles. At the beginning I was expected a number of tiles to be limited by the size of TileCache (100), but I was mistaken. Size of TileCache is growing in routine FGTileMgr::schedule_needed( ... ) to make space for all tiles. On my PC when /environment/visibility-m 500-1000km memory usage grows from 300M up to 3G an this leads to crash. Can somebody limit the value in property /environment/visibility-m or the value of variable vis in FGTileMgr::schedule_needed( ... ). The maximum value of 100km will be acceptable IMHO.

[Flightgear-devel] ufo.nas and divide by zero
Hi! I have got range exception when flying UFO. Looking in sources open that problem is in ufo.nas line 420: me.marker = Model.new(Aircraft/ufo/Models/marker.ac, geo.Coord.new().set_xyz(0, 0, 0)); When passing zeros to geo.Coord.set_xyz(), there is devide by zero in function SGGeodesy::SGCartToGeod(). This puts NAN to Elevation. Problem can be fixed in two ways: 1 Change ufo.nas to initialize geo.Coord using function set_latlon(0, 0, 0). Or was some reason to put model at the Earth center? 2 Fix SGGeodesy::SGCartToGeod() to test input point is (0, 0, 0), and put to output (0, 0, 0) without calculations. Or solve it in some other way to avoid divide by zero. Can somebody consider this and make fix in CVS?

[Flightgear-devel] access violation in FGFontCache
Hi! In GUI style I put one font for and . This give access violation error. The problem is in FGFontCache destructor. Class FGFontCache contains two Maps : TexFontMap _texFonts and PuFontMap _puFonts. _texFonts contains fonts being read from the data/Fonts. PuFontMap contains fnt structure which is referencing to texfont from _texFonts. A number of fnt structures from _puFonts can refer to a single texFont. In destructor fnt::~fnt() member fnt::texfont is deleted. But fnt::texfont is a copy of fntTexFont* from _texFonts. So when second fnt structure is deleting it try to delete the fntTexFont which was deleted at previous step. This deleting of deleted structure leads to Access Violation. Second possible problem is in FGFontCache destructor. _puFonts map is deleted here but not _texFonts map. Can this lead to memory leak?

[Flightgear-devel] Error in HUD
Hi, Some time ago I was in need to display altitude in meters on HUD. I have copied desired HUD to airplane folder and check it working. Then I change disp_scaling to 0.3048 and got strange altitude scale. As I understand we got foot scale with meter markers. After studying sources I desided that instr_item::get_value() have to return scaled value. With this I got normal altitude scales but broken roll scale. New study made it clear that problem is in the file hud_dnst.cxx. In call to instr_item() parameter data_scaling is missed: instr_item(x, y, width, height, chn1_source, options, working), Problem was fixed by changing it to : instr_item(x, y, width, height, chn1_source, 1, options, working), Can somebody fix this in CVS.

But I did not change pointed line and FG got float data without truncation due to converting to/from text form. As I wrote there were no problems with 0.9.10.

[Flightgear-devel] BUG when replay with generic protocol
I have write the flight to the file using generic protocol (with playback.xml). When replaying flight in Cockpit View all is fine, but when I switch to Chase View picture starts to jitter. I got this at Flightgear-1.0.0 at v0.9.10 this effect is not present. I build FG from sources at Windows, is someone have the same feature at other systems. And how this can be fixed?
