[Lldb-commits] [lldb] r219102 - Call SBDebugger::Initialize/Terminate from within Create/Destroy.

[Matthew Gardiner]

Ok, Thanks Ed,

I've just installed FreeBSD-10.0 (amd64) on VirtualBox. Have installed
virtualbox-ose-additions, and gnome2.

Unfortunately X (i.e. gnome) freezes on startup (i.e. won't accept kdb
or mouse input). Perhaps I should just struggle on with just running in
text mode, but having makes one so much more productive...

Matt
