This issue caused the lldb prompt to not show up in certain cases, very noticeable on Linux systems. See details on this review: http://reviews.llvm.org/D4863 And on this lldb-commits thread: http://lists.cs.uiuc.edu/pipermail/lldb-commits/Week-of-Mon-20140811/012306.html Change by Shawn Best. (Much useful help and testing by the rest of the community, thanks all!) llvm-svn: 215446
