SYMPTOMS
Dr. Watson doesn't log stack information in the postmortem debug log if the application was built by using the default settings in Visual C++ 2.x and later versions.
CAUSE
Dr. Watson can be configured to log debug information into a log file when an unhandled user mode exception occurs. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
121434 Specifying the debugger for unhandled User mode exceptions
With applications built by using Visual C++ version 1.0, the stack information includes the symbol information for the functions on the stack frame. With applications built with Visual C++ versions 2.x and later this information is no longer included. This results in an incomplete log.
This is because Dr. Watson requires that symbol information be in COFF format. By default, the Visual C++ version 1.0 link build options included both COFF and Microsoft Format debug symbols. However, with Visual C++ versions 2.x and later, this has changed; only Microsoft Format style symbols are included.
RESOLUTION
To build the application with the required symbols for Dr. Watson, the build parameters must be changed for the project. Follow these steps from within the Visual C++ integrated development environment:
- Load the desired project.
- In Visual C++ version 4.0, click Settings on the Build menu.
In Visual C++ 2.x and Visual C++ 6.0, click Settings on the Project menu.
- Click the Link tab.
- In the Category list, click Debug.
- Click to select the Generate Debug Info check box.
- Click Both Formats to include COFF and Microsoft Format symbols.
- Rebuild the application.
