PVS-Studio warning V592 for wxWidgets

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)) ) {.
