lldb's script command not working on Ubuntu #219

Open cgarciae opened 5 years ago

cgarciae commented 5 years ago

I am trying to use vscode-lldb to debug my programs, however, vscode-lldb uses the lldb's script command behind the curtains and this is crashing.

Setup

How to reproduce

Try to run the script command inside lldb

$ lldb
(lldb) script

Output:

Swift 5.1-dev

This same setup works in Swift 5.1 dev version found here, vscode-lldb works fine is this case. I notice that here python 2.7 is used whereas in S4TF python 3.6 is trying to be used.

I wonder if this issue is producible with development toolchains from swift.org/download.

@dan-zheng seeing a crash/dump running lldb; script with:

build, fwiw.
