That is utterly baffling to me.  Unfortunately, it sounds like there is 
something that's independent of which Python version you use.  Perhaps it 
is something else, then, like the OS version.  I work exclusively on 
Windows 98 SE; what OS are you on?  Also, perhaps you could try running 
individual test suites, i.e.


and see which ones crash.  It also seems bizarre to me that you're not 
getting any test output.  You should see a line of dots go by, followed by 
a "126 tests run in blah blah seconds".

Also, if there's anybody else here with Windows who can confirm or deny 
whether the binary installer version of 0.5a1 works for them, and if so, on 
what operating system, then that would be helpful.  Meanwhile, I'll try 
installing the binary version myself on a relatively fresh PC (also 98SE 
I'm afraid) and see what happens.  But I won't be able to do that until 
tomorrow or so.

There are instructions in the Python manual that's called "Installing 
Python Modules" for how to use the free MinGW tools to build 
extensions.  But I expect that won't help you since the MinGW-built modules 
are what I distributed with the binary.  Unless it's a OS or libraries 
versioning issue, in which case it might help.

No.  The persistence code from ZODB is in C, so you couldn't use PEAK for 
much then.
