OpenGL Shutdown Problem

karmalaa · 2001-06-10T22:41:42

Hi guys, upon the close up of an OpenGL sample application of mine, I get a "Invalid Address specified to RtlFreeHeap(...)" error. The stack context in which it happens to some "finalization" code within the G400ICD.dll called from the "exit()" procedure. I really can''t guess why this happens. OpenGL finalization ("wglMakeCurrent(NULL, NULL)", "ReleaseDC(hWhd, hDC)", and "wglDeleteContext(hRC)") and window destruction ("DestroyWindow(hWnd)" and "UnregisterClass()") do their job correcly. However, the problem persist. Is there something I''m missing? Hope someone can spot some Light on this problem of mine...

Guys,
that''s it!

Disabling the "bus mastering" seems to solve every problems with the G200 (under Windows 2000) of mine!

Tomorrow, at work, I''ll try and solve the problems with the G400 (under Windows NT4) in a similiar way... I''ll let you know...

See ya soon...

Bus mastering? Is that in the BIOS or a video card setting?

You can found it in the video-card setting panel. Look the ADVANCED settings within the SCREEN control panel, OPTIONS sub-folder. You should be able to find a CHECK-BOX for enabling/disabling the "Bus Mastering"...

Well, the Voodoo doesn''t seem to have that setting. Oh well, at least I figured out a way to compile without getting the error. Thanks anyway.
