  nsAutoString fileNameStr;
  // check to see if we are printing to a file
  bool isPrintToFile = false;
  mPrt->mPrintSettings->GetPrintToFile(&isPrintToFile);
  if (isPrintToFile) {
    // On some platforms The BeginDocument needs to know the name of the file.
    char16_t* fileName = nullptr;
    mPrt->mPrintSettings->GetToFileName(&fileName);
    fileNameStr = fileName;
  }

"fileNameStr = fileName;" will be fileNameStr.Assign(fileName).  So we should use Adopt, "nsXPIDLString fileNameStr", or AString parameter instead.

How severe is this leak? Is this something we should consider backporting to 56 or can it ride the 57 train?

This is small memory leak and this occurs when using [Print] - [Save as File].  Most users don't use this.

While I moved the pointer declaration in bug 1156742 (and should have spotted it :-) ), this leak has been there for over 15 years.
