Hi.

I just tried to use the Alloc() method of the IMalloc COM interface,
but it always returns 0. The following line should allow to reproduce
the problem:

var Malloc: IMalloc;
    Pointer: IntPtr;
begin
  if SHGetMalloc(Malloc)<>NOERROR then exit;
  Pointer := Malloc.Alloc(100);

SHGetMAlloc() succeeds, but Alloc(100) always returns a NULL pointer.
I have tried adding {$UNSAFECODE ON} and CoInitialize() but with no
change. I wonder if anyone else succeeded in allocating memory using
the IMalloc interface or any other way. I need the memory to store an
ItemIDList.

Thanks in advance and best regards,

Joachim
