SYMPTOMS

When creating a derived C++ class, Developer Studio exits with no warning or error message.

CAUSE

A global variable of that class was declared before the derived C++ class was defined.

RESOLUTION

Always define the class first before declaring global variables from that class.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

This problem was corrected in Microsoft Visual C++ .NET.

MORE INFORMATION

Steps to Reproduce Behavior

Open a C++ project in Developer Studio.
In one of the source files, declare the following global variable:
```
      CDerivedTest g_Test;
						
```
Position the cursor above this declaration, and begin defining the CDerivedTest class as follows:
```
      class CDerivedTest : public CBaseTest
						
```

RESULTS: Before finishing the first line of the class definition, Developer Studio will exit without warning.

In this example, writing the CDerivedTest class definition first avoids the problem.
