anton.kolesov added inline comments.


================
Comment at: lldb/tools/lldb-mi/MICmdCmdData.cpp:419
+      // Get a full path to the file.
+      std::unique_ptr<char[]> pPathBuffer(new char[PATH_MAX]);
+      lineEntry.GetFileSpec().GetPath(pPathBuffer.get(), PATH_MAX);

FWIW, If I were to write code without regard of what is being done in the same project, then I would never ever had a variable named "miValueConst5".

I am all for consistency where it makes sense, but I am also for fixing issues when we see them. 
But what is wrong with the approach of using std::unique_ptr<char[]> local variable?
