Summary: seg fault on exit in import module

Initial Comment:
Just, I'm guessing this has to do with the import
modifications you made, although I really don't know. 
I just started getting a crash which originates in
_PyImport_Fini().

When I run:
  ./python -E -tt ./Lib/test/regrtest.py test_logging

I get a core dump.  Here's the stack trace from a debug
build.  The same problem occurs in a normal (non-debug)
build.

(gdb) bt

Any ideas?

This works now, so I'm closing.  Since the problem occurred
after iconv, it was most likely related to that and Martin
fixed it.

Could this be a duplicate of #675341? You can check this by updating: Martin just fixed that bug, which was in a new unicode codec.

Hm, I wish I could reproduce this on my OSX box, but I can't: the loggin test passes just fine. I also doubt it has to do with my mods, as _PyImport_Fini doesn't touch anything that has anything to do with import hooks directly.  Of course it's still not impossible I caused this, but right now I don't see how it could.
