[lldb-dev] just me, or lldb 3.4 is very buggy?

[Greg Clayton]

You will need to update the installed libedit on your machine. "libedit" is the line reader program we use to get commands and the default version on most linux's is quite old and out of date.

Update to the latest libedit and see how many problems that solves for you.

With a new libedit and the top of tree LLDB, you will have a much better experience.
