Summary: expat causes a core dump

Initial Comment:
Raising an exception inside a StartNamespaceDeclHandler
causes
python to dump core. 

The attached program will cause a segmentation fault. 

Note it is possible to raise exception in the
StartElementHandler and
EndElementHandler

with Python 2.0
>python2.0 expat_testje.py
None 123
Segmentation fault (core dumped)

with Python 2.2.1
>python2 expat_testje.py
None 123
Segmentation fault (core dumped)

FYI, on Win2K the test program dies w/ a segfault under 2.2.3 
and under 2.3 CVS displays

None 123
Traceback (most recent call last):
  File "\code\expat_testje.py", line 19, in ?
    parser.Parse("""<tag xmlns="123">een twee drie</tag>""",

  File "\code\expat_testje.py", line 7, in 
handle_start_namespace
    raise Exception("Something is wrong here!")
Exception: Something is wrong here!

I can't reproduce the crashes for 2.3, as of today. Can
anybody else confirm that the problem has gone away for 2.3?

It appears to be fixed in 2.3, although I haven't
investigated which particular change has fixed it.
