Host = Win 7 Pro 64 bit running on top of a Dell Precision T1700 with NO video card (using integrated Intel HD Graphics P4600/P4700)
VirtualBox = 4.3.22 r98236
Guest = Xubuntu 14.10

I just created a new VM today, installed Xubuntu 14.10 into it, performed all Xubuntu updates (restarted when done), and then installed VirtualBox Guest Additions (shut down when done).

I then went in VirtualBox and changed a few of that VM's Settings, including

Display --> Video -->
 	Video Memory: 12 MB --> 64 MB
	Extended Features: Enable 3D Acceleration

When I restarted the Xubuntu VM, some things like opening a Terminal emulator work fine, but if I launch a web browser (Firefox is the install default), I get this error dialog:

(Text, in case that image hosting site drops the image: "The instruction at 0x80440033 referenced memory at 0xb0177468 The memory could not be read. Click on OK to terminate program."
EDIT: this forum refuses to display the image. Anyone know of a solution? Its URL = http://postimg.org/image/wkf4xq7c7/)

If I turn off 3D acceleration, then this bug disappears.

A web search found some related bugs: link1 and link2.

link1 had quite different symptoms, but the problem also seems to have been caused by enabling 3D acceleration.

link2 also had different symptoms, but the problem seems to have been caused by an unsigned Nvidia driver, which fails in the latest security hardened VirtualBox. I can rule out this issue on my box: following the procedure described here (i.e. run Microsoft's sigverif.exe tool), I found that my host has zero unsigned system files.

I am attaching 2 Xubuntu logs, plus all 4 VirtualBox logs, if that helps anyone to diagnose. (Both had to be packaged inside separate zip files to work around this forum's attachment size limits.)

Thanks in advance!

No one has responded to this post with any feedback, like a workaround.

Should I file a bug report with VirtualBox at this point?

Do you have and AMD video card ?
It's a known issue with the driver.
Please read ticket 12772 and 13671

Nope.

As I mentioned in my first post: "Host = ... running on top of a Dell Precision T1700 with NO video card (using integrated Intel HD Graphics P4600/P4700)"

To be precise, my CPU = Xeon E3-1245 v3 (Quad Core HT, 3.40GHz Turbo, 8MB, w/ HD Graphics P4600).

Any known problems with integrated Intel HD Graphics?

Aside: I love the latest integrated Intel HD Graphics on my Xeon, by the way. Given that I do not game, I will never ever buy a video card again! The current capabilities more than my meet my needs. For example, my Xeon can drive at least one (if not 2?) 4K monitors.

You should update the Intel video drivers. Go to intel.com

Try updating your guest additions to 4.3.22.

loukingjr: good catch.

After I installed Xubuntu into my VM, I ran thinking that that would pull down the current Guest Additions. I never looked at the version number. Obviously, it only pulled down 4.3.18 instead of 4.3.22.

It looks like 4.3.18 is not only the latest, but is the ONLY Guest Additions available in the standard Ubuntu repositories: So, do I need to pull down the 4.3.22 Guest Additions from some other repository? Any advice on the easiest and most reliable way to do this? (Apologies: I am both a linux and VirtualBox newbie.)

actually you shouldn't be using the guest additions from the Ubuntu repos at all. You should remove any VirtualBox files from your guest and install the ones that came with VirtualBox by selecting "Insert Guest Additions CD image..." from the VirtualBox Devices menu or whatever it says and install them from there.

That's another good catch. I read some bad advice on an older Ubuntu forum to install Guest Additions using apt-get.

Following the official documentation, I did these steps:
On the plus side, I now have the latest Guest Additions installed.

Unfortunately, enabling 3D Acceleration still causes the exact same fatal error: "The instruction at 0x80440033 referenced memory at 0xb0177468 The memory could not be read. Click on OK to terminate program.

I have to say that the linked page looks like a scam to me. No way I'd download their tool - it simply isn't possible to provide one fix for all bad reference at 0xnnnnn errors. That makes it snake oil or malware. Or try this other link which tells you the tool is ok? Yeah, right.

The individual cause of the error has to be fixed. In this case the advice to update the host graphics drivers sounded good to me.

It pays to be cautious but I didn't see an indication it was a scam. Better safe than sorry I suppose.

The manual fix instruction on that page is "Goto System Tools / System restore, select the most recent system restore point"

Yes, yes, I already deleted it but anything much beyond turning a PC on seems to be an advanced skill for many.
