I want to check memory error with [Rational Purify].
But test program will exit when started.
The [Rational Purify] prompted the following information:
[I] Starting Purify'd SDL_Test.exe at 2012-11-22 17:55:00
[I] Starting main
[W] PAR: GetKeyboardLayoutNameA. Length of the memory addressed by pointer is too small.... {1 occurrence}
[I] Message: SetWindowsHookEx(0x0) may not function as expected when you...
[I] MAF: Memory allocation failure of 65536 bytes in VirtualAlloc {1 occurrence}
[I] Summary of all memory leaks... {16176 bytes, 20 blocks}
[W] PAR: VirtualFree(0x7ff40000, 0x0, 0x8000) arg #1 (lpAddress) not within reserved or committed region. {1 occurrence}
[I] Exiting with code 3 (0x00000003)
[I] Program terminated at 2012-11-22 17:55:09
I do not know why. Is Rational Purify set incorrectly?

The new version (1.0.1245) has been uploaded.Modify some bugs.
A new example (examplePhysics.zip), this example for demonstration collision detection and physical simulation. (press 's' key to put an object, press 'd' key to start the simulation, simulation stop if an error occurs)
exampleFish (bin). zip: a complete example of using the 1080p resolution, demonstrates the shader.
exampleGemGame.zip: a complete game with 720p resolution.
exampleControl.zip: example demonstrates various functions, including control, video playback, audio, sequence frame, guide curves. Edited by xiajia

If you want help on this, make another topic in which the name of the topic clearly indicates the classification of the troubles you are having.
The people who can help with this type of issue are not going to look for such issues inside a topic called “Try to write a Game engine”.
