FIX: Books Online Viewer GP Faults When Using DBWIN

ID: Q114535

The information in this article applies to:

Microsoft Visual C++ for Windows, 16-bit edition, version 1.5

SYMPTOMS

Running the Viewer from Books Online causes a General Protection (GP) Fault when run with DBWIN under the Debug Kernel, but only if the Fill Buffers option is selected from the Options/Settings dialog box within DBWIN.

RESOLUTION

Books Online works properly if the Fill Buffers option is turned off in DBWIN.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Microsoft Visual C++, version 6.0.

MORE INFORMATION

Step to Reproduce the Problem

Start Windows after configuring it to use the Debug Kernel. Windows can be configured to use the debug kernel by running the N2d.bat batch file located in the Msvc\Bin directory. Note that the Debug Kernel is not installed by default, so it may be necessary to run the Visual C++ setup program again to install it. Installation of the Debug Kernel is an option when performing a Custom Installation and is available via the Tools button in the Custom Installation dialog box.

Start Windows. The Debug Kernel is active if you see "Enhanced Mode Debug Windows 3.1" in the lower-right corner of the screen.

Start DBWIN.

Under the Options menu, click Settings.

Select the Fill Buffers check box, and click OK.

With DBWIN still running, start Books Online.

Click the Viewer button. Windows generates a GP Fault.
