New issue 599: internal error at unknown location

m27315:

I have a large pytest suite with 10,000+tests, many due to the power of parameterization!  (Thanks!)  Recently, I changed the backend driver to connect via pipes for processes on localhost instead of telnet.  Anyway, after switching out the backend connection method, I receive the following backtrace:


```

```

I added the print statements are _docall to help with the backtrace's lack of information.

This seems like a bug in pytest.  Most likely there is a bug in my test, but I cannot even begin to debug this.  I wish it could tell me what line in my test caused this issue.  (It's a BIG test.)  Plus, this should result in a fail, not a pass.

Thanks for an awesome tool!
