In the following code the body of the constructor is not
executed if I use my new operator.
-------------------------------------------------------------
class TEST
{
public:
TEST( int x );
int Num();
void FAR *operator new ( size_t size );
int number;
};
TEST::TEST( int x )
{
number = x; // *LINE* //
}
int TEST::Num()
{
return( number );
}
void FAR *TEST::operator new ( size_t size )
{
GLOBALHANDLE hGmem = GlobalAlloc( GMEM_MOVEABLE, size );
TEST FAR *lpGmem = (TEST FAR *) GlobalLock( hGmem );
return( lpGmem );
}
--------------------------------------------------------------
When I call the constructor with the global 'new' operator
the constructor executes the "*LINE*" assignment and it works
fine.
TEST FAR *tp = ::new TEST( 5 ); // global new operator
But if I call it using my 'new' operator, "*LINE*" never
gets executed.
TEST FAR *tp = new TEST( 5 ); // my new operator
Looking at it with the turbo debugger I see that the code
jumps to the end of the constructor after executing my "new"
operator, i.e. it doesn't come back to the constructor to
do the *LINE* assignment.
Why?
Am I doing something wrong, or is this a bug in BC++.
Thanks for any help,
Oliver Kozber
