While adding some visual debugging aids to the collision system, I stumbled across what appears to be a bug in the SDL graphics code. I didn't want to spend much time tracking it down, so I wrote a simple test to reproduce it (and work around it in my own code).
The test program can be found at http://cvs.savannah.nongnu.org/viewvc/adonthell/test/imagetest.cc?root=adonthell&view=markup What happens is that the main loop runs once, than triggers the crash during the second iteration: Thread 0 Crashed: 0 _sdl.so 0x04de9d40 gfx::surface_sdl::put_pix(unsigned short, unsigned short, unsigned) + 192 (surface_sdl.cc:167) 1 libadonthell_gfx.0.dylib 0x004ad800 gfx::surface::draw_line(short, short, short, short, unsigned, gfx::drawing_area const*) + 560 (surface.cc:172) 2 imagetest 0x00003d58 image_test::main() + 344 (imagetest.cc:50) 3 _sdl.so 0x002d3b80 -[SDLMain applicationDidFinishLaunching:] + 76 [...] 21 _sdl.so 0x002d3ae8 CustomApplicationMain(adonthell::app*) + 604 22 _sdl.so 0x002d3bc0 main_init + 32 23 libadonthell_main.0.dylib 0x002693bc adonthell::app::init() + 1036 (adonthell.cc:237) 24 libadonthell_main.0.dylib 0x00269428 main + 72 (main.cc:81) 25 imagetest 0x0000217c _start + 760 26 imagetest 0x00001e80 start + 48 Since I'd rather invest my time into the collision stuff, I'd like to leave this one to somebody else to figure out. That's possibly a nice exercise for somebody to get a little more familiar with the code base :-).
