Thanks for investigating!<br><br>I&#39;ll keep watching. I&#39;m currently developing a small Django app, and the crash happened during one of the automatic reloads that the development server do whenever a source code file changes. The problem is that I probably ran through the same procedure several hundred times over the past few weeks, but the bug happened only *once*. Seems like a nasty bug. I *suspect* it may be thread related, a racing condition or something like it. (and yes, I&#39;m using a regular build, not a debug build).<br>

<br>Also note that I use Python since 1998 and never, in the past 12 years, I had a dump like this.<br><br>As for this ticket, it seems like a nasty and elusive bug; I _feel_ that we may never see the same bug again, _but_ other people may encounter similar situations, and we can then try to correlate them to find the cause. If I don&#39;t manage to reproduce it over the next few days we may close it but keep it in the tracker, until someone else hits it again.<br>

<br>
Clearly not enough information, but I have a few observations:<br>
<br>
1. Clearly the crash occurs on exit (in Py_Finalize) during a module cleanup.  (Unfortunately it looks like a non-debug build of Python was used so figuring out which module is involved may be hard.<br>
<br>
2. Memory map suggests that the crash is very late in python finalization.  Note that only two python modules are still mapped: mxDateTime and _hashlib.  However the memmap seems incomplete.<br>
<br>
Try to reproduce the crash with a debug build of python (configure --with-pydebug).  The debug build may also crash sooner and more reliably.<br>
