Examples of errors detected by the V592 diagnostic

V592. Expression is enclosed by parentheses twice: ((expression)). One pair of parentheses is unnecessary or typo is present.


wxWidgets

V592 The expression was enclosed by parentheses twice: ((expression)). One pair of parentheses is unnecessary or misprint is present. wxscintilla lexau3.cxx 781


static void FoldAU3Doc(....)
{
  ....
  // if a keyword is found on the current line
  // and the line doesn't end with _ (continuation)
  // and we are not inside a commentblock.
  if (szKeywordlen > 0 && (!(chPrev == '_')) &&
      ((!(IsStreamCommentStyle(style)) || foldInComment)) ) {
  ....
}

This is what should have been written here: if (szKeywordlen > 0 && (!(chPrev == '_')) && (!(IsStreamCommentStyle(style) || foldInComment)) ) {.

Similar errors can be found in some other places:

  ....
  uint64 value = hex.value;
  uint64 width = hex.spec;
  // We accomplish minimum width by OR'ing in 0x10000
  // to the user's value,
  // where 0x10000 is the smallest hex number
  // that is as wide as the user asked for.
  uint64 mask =
