BUG: CV: Trace Does Not Step Into Some MOVE Overlay Functions (116300)

MORE INFORMATION

The sample program shown below can be used to demonstrate the problem. After building a debug version of the program, start Codeview, load the .EXE, and press F8 three times. Codeview will not step into the first function, Overlay1Func1(). Codeview will, however, step into Overlay1Func2() and Overlay1Func3. Also, at this point the VS command (View Source) does not work on Overlay1Func1().

Sample Code

/*  OVERLAY.H
*/ 

int Overlay1Func1(void);
int Overlay1Func2(void);
int Overlay1Func3(void);
int Overlay2Func1(void);
int Overlay2Func2(void);
int Overlay2Func3(void);

/*  MAIN.C

    Compile options needed:  /c /AL /G2 /Gy /Zi /Od
*/ 

#include "overlay.h"

void main( void )
{
    Overlay1Func1();
    Overlay1Func2();
    Overlay1Func3();
    Overlay2Func1();
    Overlay2Func2();
    Overlay2Func3();
}

---------------------------------------------------------------------

/*  OVERLAY1.C

    Compile options needed:  /c /AL /G2 /Gy /Zi /Od
*/ 

#include "overlay.h"

int Overlay1Func1(void)
{
    int i = 1;
    i = i * 2;
    return i;
}

int Overlay1Func2(void)
{
    int i = 2;
    i = i * 2;
    return i;
}

int Overlay1Func3(void)
{
    int i = 3;
    i = i * 2;
    return i;
}

---------------------------------------------------------------------

/*  OVERLAY2.C

    Compile options needed:  /c /AL /G2 /Gy /Zi /Od
*/ 

#include "overlay.h"

int Overlay2Func1(void)
{
    int i = 1;
    i = i * 2;
    return i;
}

int Overlay2Func2(void)
{
    int i = 2;
    i = i * 2;
    return i;
}

int Overlay2Func3(void)
{
    int i = 3;
    i = i * 2;
    return i;
}
