Missed semicolon

PVS-Studio warning: V504 It is highly probable that the semicolon ‘;’ is missing after ‘return’ keyword. AdvancedSettings.cpp:1476

void CAdvancedSettings::SetExtraArtwork(const TiXmlElement* arttypes,
   std::vector& artworkMap)
{
  if (!arttypes)
    return
  artworkMap.clear();
  const TiXmlNode* arttype = arttypes->FirstChild("arttype");
  ....
}

The code formatting suggests the following execution logic:

• if arttypes is a null pointer, the method returns;
• if arttypes is a non-null pointer, the artworkMap vector gets cleared and some actions are then performed.

But the missing ‘;’ character breaks it all, and the actual execution logic is as follows:

• if arttypes is a null pointer, the artworkMap vector gets cleared and the method returns;
• if arttypes is a non-null pointer, the program executes whatever actions come next but the artworkMap vector doesn’t get cleared.

To cut a long story short, this situation does look like a bug. After all, you hardly expect anyone to write expressions like return artworkMap.clear(); :).
