Problem with embedded python

[ugodiggi]

I have the following code, that seems to make sense to me.

However, it crashes about 1/3 of the times.

My platform is Python 2.4.1 on WXP (I tried the release version from
the msi and the debug version built by me, both downloaded today to
have the latest version).

The crash happens while the main thread is in Py_Finalize.
I traced the crash to _Py_ForgetRefer ence(op) in object.c at line 1847,
where I have op->_ob_prev == NULL.

What am I doing wrong? I'm definitely not too sure about the way I'm
handling the GIL.

Thanks in adv for any suggestion

Cheers and ciao

Ugo
