Unofficial VirtualDub Support Forums > Testing / Bug Reports > [v1.9.10] Virtualdub Crashes Recently With Oob Mem

Posted by: nash Nov 5 2010, 03:52 AM

Recently my Vdub has been crashing sometimes when I take actions in other programs, such as launching other programs while Vdub is sitting idle in the background. For instance, it just crashed when I launched my CD ripping program to rip a new CD I purchased. It's also crashed when I launch the Curse Client (used for managing WoW addons) and clicking on New Email in Outlook. At one time I did notice that I had two VDubs open, one was using the Directshow filter to edit an MKV and one was open with an MPEG-2 VOB using fcchandler's MPEG2 plugin. The MKV one crashed while the VOB one did not. Perhaps it is related somehow to the Directshow plugin? It can crash while doing a dub or while sitting idle with just a file open.

Vdub (with the same plugin set) has been stable for me for a long time, and the only thing I can think of that I changed on my system recently was updating my video drivers to a newer version - could this possibly be related somehow through DirectX/Directshow?

Each time it crashes, it's always an out of bounds memory access:

An out-of-bounds memory access (access violation) occurred in module 'VirtualDub'...
...reading address 6321CC10.

Is there a debug version I can run to perhaps drill further into this?
