Description
Note: Migrated from the vscode repository
- VSCode Version: Code 1.19.3 (7c4205b5c6e52a53b81c69d2b2dc8a627abaa0ba, 2018-01-25T10:25:01.248Z)

Steps to Reproduce:
- Create a 'fresh'
launch.json. - Launch ipython.
- Pick
(lldb) Attachfrom the debugging drop-down menu. - Run Python script from ipython, lldb stops at breakpoint in C++ code, as expected.
- Unable to
SteporContinuefrom the debugging menu. Have to hitDisconnecttwice to disconnect.
After this, Ipython is still running, but unresponsive. I have to 'Force quit' it from the Activity Monitor (process that needs to be killed is called lldb-mi).
Reproduces without extensions: Yes (with cpptools of course)

Research direction
Start with the fresh launch.json and reproduce the lldb + ipython session using the listed VS Code and cpptools versions. Investigate the attach, Step, Continue, and Disconnect behavior around lldb-mi; the issue is done when stepping and continuing work and ipython remains responsive without force-quitting lldb-mi.
