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

[Pavel Labath via lldb-dev]

Hi Gábor,

sorry for the late reply, I have been OOO. Thanks for the detailed
report. I think the fact that we load the system lldb from the unit
tests should be considered a bug. I am going to try to find some time
fix this issue.

thanks,
pl
