python2.6_dに御光臨願う前に思い出した、Py_FinalizeとBoost::pythonの絡みの件

> Embedding - 1.39.0

Getting started
Being able to build is nice, but there is nothing to build yet. Embedding the Python interpreter into one of your C++ programs requires these 4 steps:
#include
Call Py_Initialize() to start the interpreter and create the _main_ module.
Call other Python C API routines to use the interpreter. Note
Note that at this time you must not call Py_Finalize() to stop the interpreter. This may be fixed in a future version of boost.python.
(Of course, there can be other C++ code between all of these steps.)
Now that we can embed the interpreter in our programs, lets see how to put it to use...

ま、まじでーー

% grep -r Py_Finalize ~/Sources/boost_1_39_0/libs/python/test/*.cpp  
/home/*/Sources/boost_1_39_0/libs/python/test/exec.cpp:  // Boost.Python doesn't support Py_Finalize yet.
/home/*/Sources/boost_1_39_0/libs/python/test/exec.cpp:  // Py_Finalize();
/home/*/Sources/boost_1_39_0/libs/python/test/import_.cpp:  // Boost.Python doesn't support Py_Finalize yet.
/home/*/Sources/boost_1_39_0/libs/python/test/import_.cpp:  // Py_Finalize();

ま、まじだーー！！

あれから5日後・・・
結論：Py_Finalizeはまったく関係ない気配。ナンテコッタ
SIGSEGVをなくすには、継承グラフのルートにclass_("Hoge", no_init)を設ければ大丈夫
とにかくno_initが含まれる定義から継承させれば回避できる　・・・今のところは。
原因は相変わらず不明
