The following runs to completion under 8.38 but crashes if compiled with 8.39.

Am I breaking a rule somewhere? The code this was extracted from has been fine for years.


#include <stdio.h>

//
// The EXE produced by DM 8.39 crashes with this code!
//

// compile with "sc rickbug -mn"


class IFScrnRect
{
public:

IFScrnRect()           {}
virtual ~IFScrnRect()  {}
};


class SelectableObject
{
//
// Note: the bug disappears if the "static" RectUpdate() is renamed to
// something different.
//

public:

SelectableObject()            {}
virtual ~SelectableObject()   {}

static void RectUpdate()      {}

virtual void RectUpdate(int cmd);

};

void SelectableObject::RectUpdate(int cmd)
{
// this is what we expect main() To call

printf("RectUpdate:cmd is %d\n",cmd);
}

class BadText : public IFScrnRect,
public SelectableObject
{
public:

BadText()            {}
virtual ~BadText()   {}
};


main()
{
printf("1");
BadText * t = new BadText();
printf("2");

// DM 8.39 crashes here. v8.38 and SC 7.5 are OK
//
// In the full application it seems it was calling the wrong function.

t->RectUpdate(123);
printf("3");
delete t;
printf("4");

return 0;
}

Fixed in 8.40.
