[C++-sig] Memory management in Boost.Python

[Ernie Lee]

Hi Stefan,

  I updated my code so it now use 'boost::shared_ptr' class while
specifying the held-type and i got exactly the same errors (i guess boost
did recognize class even in different namespace).

  Any other theories of what could be wrong? Could it be that Python in
some cases tries to manage memory directly, disregarding SP layer?

  Thanks,

Ernie.
