In combination with the patch in #4213, subinterpreter.patch fixes the
problem.
I'm assigning the bug to Barry for his final decision.

The patch subinterpreter.patch is based on Martin's patch
importexc.diff. The patch contains additional code to setup a
preliminary stderr object and a call to initstdio(). Amaury is right. I
had to add initstdio() to initialize the standard
Martin v. Löwis [EMAIL PROTECTED] added the comment:
Here is a patch that fixed importexc.c. It consists of the following parts:
- set m_size of the builtins module and the sys module to -1, indicating
that these modules don't support repeated initialization. This should be
reviewed; perhaps
Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:
I think the patch goes in the right direction.
But in addition, Py_NewInterpreter() has to call initstdio() between initmain()
and initsite() (the same sequence as in Py_InitializeEx)
Found by using the following command string in
Benjamin Peterson [EMAIL PROTECTED] added the comment:
Wouldn't it make more sense to move interpreter initialization things to
Py_NewInterpreter and call it from Py_InitializeEx?

Can you propose a specific patch? I'm worried that doing so blindly
introduces other bugs.

Graham Dumpleton [EMAIL PROTECTED] added the comment:
Adding the functions as initfunc in module init table is of no use as
they aren't invoked when creating a sub interpreter.
One thing that does appear to work, although no idea of whether it is
correct way to solve problem, is to duplicate
Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:
Your patch may go in the right direction, but please provide only
context diff or unified diff files.
Use diff -du, or svn diff to generate the file.

Argh. Personally I like to provide context diff's but more often than not
get abused for providing them over a unified diff. Was in a hurry this
time as had only a couple of minutes of battery life left on the laptop,
so quickly did it

Maybe, I'm not seeing the whole problem, but can't we just add
_PySys_Init and _PyBuiltin_Init to config.c like in the attached patch?
Obviously, we will eventually want to make a separate state to store
module globals in, but I think this

New submission from Amaury Forgeot d'Arc [EMAIL PROTECTED]:
The example Demo/embed/importexc.c crashes, because Py_NewInterpreter
cannot reimport builtins and sys modules. This problem seems important
for embedding applications like mod_python, for example.
