Browse Source 
clangcompletionassistprocessor.cpp: 136
CID 1475671:  Possible Control flow issues  (DEADCODE)
  Execution cannot reach the expression "codeCompletion.completionKind
  != ClangBackEnd::CodeCompletion::SlotCompletionKind" inside this
  statement: "if (slotCompletion && codeC...".

clangbackendcommunicator.cpp: 272
CID 1475649:  Null pointer dereferences  (NULL_RETURNS)
  Dereferencing a pointer that might be null "document" when calling
  "contents". (The dereference happens because this is a virtual
  function call.)

clangutils.cpp: 335
CID 1475678:  Error handling issues  (CHECKED_RETURN)
  Calling "open" without checking return value (as is done elsewhere 144
  out of 158 times).

codecompletionsextractor.cpp: 48
CID 1475676:  Uninitialized members  (UNINIT_CTOR)
  Non-static class member field
  "currentCxCodeCompleteResult.CompletionString" is not initialized in
  this constructor nor in any functions that it calls.
