View Full Version : glCallList in debug mode = crash...

Hi, I'm not even sure if the prob lies in GL or Visual Studio but maybe some of you had the same problem before http://www.opengl.org/discussion_boards/ubb/smile.gif

All of my code worked fine until recently; the problem is rather quite strange. It's sometimes repeatable but don't wanna repeat it anymore because the entire system crashes -> as in the Num Lock key doesn't toggle, mouse doesn't respond, I don't even get the blue screen; just the whole system lock up requiring a power reboot - I don't think my HD likes that http://www.opengl.org/discussion_boards/ubb/frown.gif

The code runs fine without any error but when I debug the code (Visual Studio C++, SP5), it does the hard crash at the glCallList call whether I stop there or go past it. I've made sure that I'm not storing any of the illegal http://www.opengl.org/discussion_boards/ubb/smile.gif calls in the display list. I'm just doing like 100 textured quads in the display list.

I've heard that sometimes it crashes when you have watch window open; I tried but didn't help. I've never seen debugger crash... can you debug the debugger? http://www.opengl.org/discussion_boards/ubb/eek.gif

I'm using Oxygen GVX1 with the lastest driver on Win2000 Pro SP2.

As always, I welcome any comments.

I remember having the same problem several years ago when developing on an early 3D labs OpenGL card. I believe the crash you're experiencing is in the video driver. The only thing I was able to do was to force my program to choose a software renderer when I was debugging. Very annoying, but I'm not sure there's anything else you can do.

that's not good... I don't think 3D Labs release drivers anywhere near often as other venders (nVidia, ATI), for my card anyways.

Don't wanna use software if possible http://www.opengl.org/discussion_boards/ubb/frown.gif

Thanks for your reply, dslater. Anyone else have other suggestions?
