Yes it is always the first thing I do after an update.

I also get a core dump while importing OIBTree :

import zodb.btrees._OIBTree # dynamically loaded from 
/cygdrive/c/zope3head/zope
3/src/zodb/btrees/_OIBTree.dll
Segmentation fault (core dumped)

There's a new Cygwin Python 2.2.2. I'll get it first and tell you about 
it. If the problem is still there I'll try to build Python with debug on.

Can you tell me what options need to be passed to make a debug build ?
A quick search did not help me.

Thanks
