Hi All,

It seems that CoMarshalInterThreadInterfaceInStream can be called only
32,769 times in a row on a pointer
to some COM object without balanced CoGetInterfaceAndReleaseStream calls.

I receive a pointer to COM component and I
CoMarshalInterThreadInterfaceInStream it to process it on another thread
(involves sending the
data it contains over a socket). So, I can easily have more
CoMarshalInterThreadInterfaceInStream calls before they are actiually
processed.
Never thought it would have a limit like that.

The error I get back is 0x8007000E -"Not enough storage is available to
complete this operation. " But the whole process hardly takes 10 megs and
the overall
memory is not even 25% used.

Imaginary ex.:
  IUnknown* pUnk;
  HRESULT hr = CoCreateInstance(CLSID_Something, 0, CLSCTX_INPROC,
IID_IUnknown, (void**)&pUnk);
  IStream* pStream;
  int i =0;
  while(true)
  {
   i++;
   hr = CoMarshalInterThreadInterfaceInStream(IID_IUnknown, pUnk, &pStream);
   ATLASSERT(!FAILED(hr));
  }

It should assert fairly quick and i will always be equal to 32,769
