Release Version Only Problem..

this simple.. class include member variable CString,
make many object and free. but programe using memory
size is big and big..(only release version, debug version
is correct)

========exam code==============
#include <afxtempl.h>
class CObj:public CObject
{
public:
__int64 a,b,c,d,e,f,g,h;
CString sa,sb,sc,sd,se;
};
void TestFunc()
{
CTypedPtrArray<CPtrArray,CObj*> m_array;
CObj *p;
for (int i=0;i<120000;i++)
{
p=new CObj;
p->sa="123";
m_array.Add(p);
}
for (i=0;i<m_array.GetSize();i++)
delete m_array[m_array.GetSize()-i-1];
m_array.SetSize(0);
}
 
I put a call to TestFunc into a loop, and do not see the process memory (viewed in task manager) grow between iterations. The
memory looks to be correctly allocated and freed. On each iteration the memory grows from ~7megs to ~33megs, then falls
back to ~7megs. The behavior was the same for debug or release, and using VS .Net2002 and VS .Net2003.

When you call TestFunc in a loop do you see the process allocation grow between iterations? What version of Visual Studio
are you using?
