So could anyone share your experience with this issue, provide some test case or anymore information about this issue? I will try to solve it.

I haven't been able to spend any time on this. But the general approach I wanted to check is as follows:

Test 1 (to check registry operation):

  1. Use an example which embeds (not extends) python.
  2. Register a type X to be converted to C++ type XC.
  3. Perform some operations to verify that step 2 works.
  4. Call PyFinalize.
  5. Restart python vising PyInit...
  6. Check that X does not convert to XC.

Test 2 (to check object cleanup):

  1. Hold weak pointers to some shared_ptr objects exposed to python.
  2. Call PyFinalize.
  3. Ensure that all the weak_ptrs point to deleted objects.

Let me think about this some more. Please try pinging Dave A directly to make sure he has no tests for you to try.
