The new Python 2.4 crashes when starting some of my
programs. This happens under win xp as well as under
win nt. The crashes are reproduceble, but I didn't
succeed in finding the exact place where it happens.

In the attachment you find a Dr. Watson logfile. I hope
it helps. Otherwise I think I will be able to help with
more information.

Thanks in advance

I have the same or similar problem.
While python24.dll(Python 2.4 for Windows) uses msvcr71.dll 
for CRT, host C++ program embeding Python 2.4 as a script 
engine, in my project, is compiled by VC++ 6.0 (msvcrt.dll).
So, the following code snip makes a crash.

FILE* fp = fopen("somecode.py", "rt"); // uses msvcrt.dll
PyRun_SimpleFile(fp, "somecode.py); // uses msvcr71.dll 
inside. Cause of a crash.

In my case, I must use VC++ 6.0 and I want clients of my 
program to install Python 2.4 from www.python.org.
How do I solve this problem ?

The FILE pointer is specific to your c-lib.
Different versions of the ms c-lib have incompatible
implementations of this structure.

To work arround such problems use python to get the right FILE*

Example (not tested):

/* use pythons std c library to produce a FILE object
   to avoid mess with different c libs in debug or release mode
   and different versions used to compile python
*/
      PyObject* pyFile = PyFile_FromString(fileName, "r");

      FILE* const file = PyFile_AsFile(pyFile);
      assert(0 != file);
      const int succ = PyRun_SimpleFile(file, fileName);
      // now remove py file object
      Py_XDECREF(pyFile);

Any objections to marking this as Invalid and closing the bug?

Sorry, the attachment was not appended. By the way, the
problem  occurs without any external modules/libraries. It
just juses python-source. The problem might be connected
with the use of module array.

Can you create a small test case that demonstrates the problem?

Okay, I finally was able to produce a small example. When I 
start python from the commandline with 
file "Lebenserwartung.py" python crashes. It doesn't crash 
when I remove the coding-line (1st line) of 
file "Sterbetafeln.py".

(The example can't run properly due to missing files, but 
these don't influence the crashes)

This sounds like it might be related to bug 
http://www.python.org/sf/1076985. Can you retry your 
scripts with the patch from 
http://www.python.org/sf/1076985? What happens if you 
replace the "cp1252" in the encoding header with "iso-8859-
1"?

A quick workaround might be to wrap the long source lines in 
Sterbetafeln.py.

That's it!!! I applied the patch to codecs.py and now it works 
without crash!

Thanks a lot!

Let's close this thread.
