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.

Any ideas?

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.

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

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