[lldb-dev] lldb on Ubuntu 14.04 is unusable

[Todd Fiala]

Hey Eran,

Thanks for the update on 14.04!  Glad to hear the real machine install is
working.  It might be worth you filing the protection error bug with the
VirtualBox folks.

I expect sometime soonish we'll be upgrading to Ubuntu 14.04 over here, in
which case that'll be where I spend much of my time.

Sincerely,
Todd Fiala
