[lldb-dev] Linux: Failing lldb unit tests and TestLinuxCore.py

[Pavel Labath via lldb-dev]

The core file tests should be fixed as of r335859. I tried reproing
the python unit tests problem, but I couldn't get it to fail that way.
I can help you get to the bottom of it if you're interested, but it's
going to take some interactive debugging (for start I'd need to see
the link command for the test binary in question).

cheers,
