T3D 1.1BETA 1, 2 and 3 BLUE SCREEN OF DOOM! Possibly reflections - RESOLVED

WTF? Bad crash of some kind. Right-click and select "view image" for it's full bizarreness.
And yes, that clock does say 05:15, which is why I'm running a trace now.
All the "speckles" are flashing and it's all over the desktop. New_Project.exe stops responding. Flashing "speckles" remain on the screen after closing the application. Requires a reboot to clear them.
GTS250 (Galaxy), latest driver, Win7 with Aero.
Obviously you can see a rocket, a cloud layer and thus lot's of relection - which is what I'm thinking/wildly stabbing in the dark at is the issue here. That's a big old lump of water plane to reflect stuff, that is.
Problem is when running from a Debug I get a full blown BSOD, so it's not possible for me to call a stack.
If I turn FullReflect off, it doesn't crash or glitch when I do the same thing.

I went back and looked and this bug was introduced in July 2009 by one of our more experienced devs and none of the debugging tools out there could detect it. It took an NVidia engineer to give me a hit as to the crash within the driver to put me on the right track.
And as bad as this was ATI cards didn't mind it at all.

edit: I'll take a look at #95 again and see if this resolves it.

@Tom - applied your fix, but not the #95 bit. When I have 3 vs 3 AI and 1 player in the game shooting projectiles like there is no tomorrow. After a few minutes the game crashes. Compiled it back to stock 1.1 B3 projectile.cpp and .h and I did not get this crash for about 10 minutes. Something not clearing down or overflowing perhaps. Any ideas?edit: I'll take a look at #95 again and see if this resolves it.

@JulianR from what I understand the #95 bit is the true fix for it, the other was his first attempt. Try applying just that (that's all I did) and see if that resolves the issue for you.

Cheers Sean. Giving it a go now. Rough count is about 70-80 projectiles firing before crashing.
#108
Edit: it must be down to my build with AI. I can fire 1000 projectiles rapidly from 1 player no problem. Or it could be a completely different problem :) This one is going to be fun to resolve!
01/30/2011 (7:06 am)
Still crashes, but takes longer with #95 applied... around 200-300 projectiles firing with 6 AI and 1 player. If anyone can try the same with bots for me this will make sure it's not just my build. I'll do a debug and see what that brings up.Edit: it must be down to my build with AI. I can fire 1000 projectiles rapidly from 1 player no problem.

@Julian - If your not seeing graphical corruption and/or full screen flickers then its probably a different bug.
#110
01/30/2011 (8:35 am)
@Tom - yeah, graphical corruption is now fixed. The two appear not to be related. I'll post a new thread once I've dug a little deeper. Thanks.
