It also fits in with my workaround, as someone commented 'if you import pyexpat first, it looks fine', which is effectively what I am doing. Many thanks for the response.

I thought that a error like this in a standard module would be of some concern, even if it turns out that the fault is with wxPython. Anyway, I have found a workaround. I call sax.make_parser() from the main line of the program, before starting the wxPython main loop. The reference it returns is global, and can be used anywhere within the program. This seems to work ok. Frank -- http://mail.python.org/mailman/listinfo/python-list
sax.make_parser() segfaults
Hi all I am using Python 2.4.1. I have machines running FC4, RH9, and MSW Server 2003 for testing. If I call sax.make_parser() from the interpreter or from a stand-alone program, it works fine on all machines, but in the following setup it works correctly on MSW, but segfaults on both FC4 and RH9. The setup is a client program running wxPython as a gui, and Twisted as a means of connecting to a server. Both wxPython's and Twisted's main loops seem to be running ok. I have made a remote call to a Twisted server, which has returned an xml string. In the callback routine, I print the xml for debugging purposes, which looks fine, then I call 'parser = sax.make_parser()'. At that point it segfaults. I added a 'print sax' command just before the call to ensure it is valid. It displays module 'xml.sax' from '/usr/lib/python2.4/xml/sax/__init__.pyc', which looks correct. A little digging reveals that the segfault occurs in xml/parsers/expat.py, when it tries to execute 'from pyexpat import *'. On FC4 and RH9, pyexpat.so is in python2.4/lib-dynload. On MSW, there is a pyexpat.pyd in Python24/DLLSs, and a pyexpat.lib in Python24/libs. I don't know if any of this is relevant, but I thought I would supply as much info as possible. As mentioned above, I do not have the problem with MSW. Any suggestions will be much appreciated. Thanks Frank Millman -- http://mail.python.org/mailman/listinfo/python-list
