I found the race condition in: ScriptInterpreter *CommandInterpreter::GetScriptInterpreter(bool can_create); More than one "ScriptInterpreter *" was being returned due to the race which caused any clients with the first one to now be pointing to freed memory and we would quickly crash. Added a test to catch this so we don't regress. <rdar://problem/28356584> llvm-svn: 289169
