In my point of view it would be helpful when debugging to disable code optimization since when I debug an VisualGDB application  it is jumping like a “crazy horse through” the code …

In the VisualGDB project settings I added the -O0 (disable code optimizations completely) but it doesn’t change anything.

Useful tips but not what I am looking for at the moment: http://visualgdb.com/debugging/

Example: pDevice == NULL:

    47: GELinBeeper::GELinBeeper(const char *pDevice)
    48: {
    49:    if (pDevice == NULL)
    50:    {
    51:        _pDevice = (char *)DEFAULT_BEEPER;
    52:    }
    53:    else
    54:    {
    55:        _pDevice = (char *)pDevice;
    56:    }
    57: }

Breakpoint at 49:
47, 51, 55, 51, 57

Or is there something wrong with my settings?
