[Lldb-commits] [PATCH] D134037: [lldb] Fix CommandInterpreter::DidProcessStopAbnormally() with multiple threads

[Martin Storsjö via Phabricator via lldb-commits]

mstorsjo added a comment.

Added a testcase. I'm not sure if this is the most accurate/correct place for the test, but the name is at least verbose enough to describe what it exercises.
