"Error--buffer overrun" and "Runtime Error!" error messages when you open a Visio 2002 or CAD drawing file (307705)

SYMPTOMS

In Microsoft Visio, when you open an AutoCAD drawing and then save the file as a Visio (.vsd) or AutoCAD drawing (.dwg), you may be unable to open the resulting .vsd or .dwg file in Visio or AutoCAD. For example, when you attempt to open the .vsd or .dwg file in Visio, you may receive an error message similar to the following:

Error--buffer overrun.
This file may be an AutoCAD R14 beta format file.

When you click OK in response to the error message, you receive the following error message:

Runtime Error!
Program:\Program Files\Microsoft Office\Visio10\Visio.exe

abnormal program termination

When you click OK in response to this error message, you receive the following error message:

The instruction at "xxxxxxxxxx" referenced memory at "xxxxxxxxxx". The memory could not be "read".
Click on OK to terminate the program.

When you click OK, Visio quits.

CAUSE

This behavior can occur if the size of the original AutoCAD drawing is 2 megabytes (MB) or larger. When you save an AutoCAD drawing as a .vsd or .dwg file, Visio may not handle the save operation correctly with some CAD drawings of this size or larger.
