Martin, I think this has to do with your changes to
iconv_codec.
After cvs update; configure; make, I get a seg fault on
exit of the interpreter after doing nothing other than
typing ctrl-D. This is on Linux (RedHat 8.0).

And the reason I think Martin has something to do with
it (note the tp_name field):

This is fixed in _iconv_codec.c 1.4.
I'm surprised that it happens in this way for you, though,
since normally, importing site.py won't import _iconv_codec.
The only explanation is that you have changed site.py in
some way.

The reason _iconv_codec got imported is because I have
JapanesCodecs installed which is imported by addpackage in
site.py. And JapaneseCodecs imports encodings which in turn
imports iconv_codecs.
Things work now thanks to your fix. Thanks.
