When using a threaded version of perl, I'm getting a segmentation fault when I run any of the tests. I've tested this with the 5.8.0 w/out threads and the tests pass fine.

Here's a trace of the fault:

It's happening after the 'exit 0' in t/00base.t. It also happens in every other test script as the script tries to do a dbi login. Here's a sample from t/40listfields.t

I'm at the end of my debugging abilities in this arena. Any suggestions?
