Q45241: Setting a Breakpoint Highlights More Than One Line

When setting a breakpoint, CodeView may highlight two or more lines of
code when you do the following:

1. Compile C program (e.g., "Hello, world") with /Zi /Od.

2. Load CodeView with 50 line mode (in VGA mode) as follows:

      cv /50 hello.c).

3. Display mixed source and assembly.

4. Move the cursor to the edit window and scroll down two or three
   pages of start-up assembly code.

5. Set and remove breakpoints at arbitrary locations. In some cases,
   multiple lines will be highlighted and the display altered. The
   code itself is not changed. To restore the altered display, page
   down and then page up to the altered location.

CVP does display this problem.

Microsoft has confirmed this to be a problem in CodeView Version 2.20.
We are researching this problem and will post more new as it becomes
available.

After setting a breakpoint that highlights more than one line of code,
using the BL command will list only the one breakpoint you set.
