Embedded python debug build crashing.

I'm trying to embed Python 2.3.5 into a C++ application on Windows XP.
When I build my app with debug symbols and link to a debug build of
Python, then my program seems to crash most (but not all) of the time.
Sometimes it crashes on startup, and sometimes at exit, sometimes not at
all. I haven't seen it crash with non-debug builds of my app and
Python. The release build runs my Python test code just fine. When the
debug build doesn't crash at startup, it gets through some, but not all
of my test code. It still crashes even if I only run Py_Intialize() and
Py_Finalize(). My app is multithreaded, but Python only runs in the
main thread.
I use Visual Studio .NET 2003 7.1. If I understand things correctly,
that means I need to recompile Python, since the prebuilt binaries are
compiled with MSVC 6. I've compiled both debug and non-debug versions
of Python. I'm sure that I'm linking my app to the correct build type.
I'm also pretty sure that I'm setting the PYTHONHOME environment
variable correctly so that my app is trying to use the right Python
runtime. Windows has a trick where, if my app's executable is called
app.exe, then the presence of a file called app.exe.local in the same
directory will force my app to use local copies of DLLs first. I've
used that, so I'm pretty sure I'm not accidentally using the wrong DLLs
at runtime.
I've googled and couldn't find any similar problems. Is there something
simple I'm forgetting to do? I'm out of ideas. Does anybody have any
ideas about how to attack this problem?

Thanks,

Adam Tomjack

Python 2.4 is built with Microsoft Visiual C++ 7. This means that it uses msvcr7.dll, which *isn't* a standard part of the windows operating system. This means that if you build a windows installer using distutils - it *requires* msvcr7.dll in order to run. This is true even if your package is a pure python package. This means that when someone tries to use a windows installer created with Python 2.4, on a machine with only python 2.3 - it...

I'm embedding a Python interpreter into a project, and compiling with MSVC. It all runs great in the "Debug" configuration, but everything gets scary when I switch to "Release". I've read about things that can go wrong when you use the wrong runtime library when compiling a program that uses Python. I've done my best to follow the suggestions I've read, but I still seem to be having trouble. Here's a summary of how I've configured my...

I have a dll/so which embeds python. I can verify it works by compiling it as an executable and adding an appropriate main. I tried to write unit tests for this library with ctypes and a simple python script. Access violations and other strange things result. I suspect this is because I am basically embedding python in python at this point. How can I make my dll/so with embedded python support use via ctypes?

Hello, I'm trying to write a program to send python statements to a python server via tcp and then get back results via a tcp connection. It nearly works ... but I'm totally lost with the embedded dictionary (I'm quite new to python). The first part of the server start the python interpreter via Py_Initialize() and then waits for python statements. To send command, I get some strings and evaluate them through PyRun_String.

I am embedding Python in a MSVC++ (2005) application. The application creates some environment and then launches a Python script that will call some functions exported from the MSVC++ application. I want to be able to debug the Python script by using a debug server, like Winpdb (winpdb.org). I use ActivePython 2.5.2.2, Microsoft Visual Studio 2005, and Winpdb 1.3.8.
