SYMPTOMS
Codeview for Windows may not break at the right location or may not break at all if a conditional breakpoint is set on a variable of type double. Conditional breakpoints include breakpoints such as "Break when Expression has Changed" and "Break when Expression is True". Codeview for MS-DOS does not have this problem.



RESOLUTION
If you have Visual C++, use the Visual Workbench debugger instead of Codeview for Windows.



STATUS
Microsoft has confirmed this to be a problem in Codeview for Windows version 4.0, 4.01, and 4.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



MORE INFORMATION
The program listed below can be used to demonstrate the problem. Build a debug version of the program, load it into Codeview for Windows, and enter the following commands in Codeview's command window:

bp = x

bp = y

bp = z

g ; breaks are either missed or break at wrong location

Sample Code
/* Compile options needed: /Zi /Od


 * 1) include 

double x, y, z;

void f( void ) {   x++; y++; z++; }

int PASCAL WinMain (HANDLE hInstance, HANDLE hPrevInstance,          LPSTR lpszCmdLine, int nCmdShow) {   f; return 0; }

Additional query words: 4.00 4.01 4.10
