When I run some of my Mac OpenGL apps (coded using GLUT) they sometimes crash. This has become more and more of a problem. The problem occurs during the loading of textures using TK to load RGB images. If I am running the debugger when it crashes it says that it was an unmapped memory error. Then when I look through the memory addresses of the GLuints which I am using to store the index to the texture it says “register not available” where it normally says the address. What’s going on here? Note on hardware & software: A 233Mhz iMac (Rev B) w/MacOS 8.6, OpenGL version 1.1.2 & 1.1.3 (I have tried both versions with the same results), and CodeWarrior Pro 5 as my compiler. Sometimes the apps work fine though. Any help would be appreciated.
