    Description

      If I run MOC on the following header file:

      #pragma once
#include <QObject>

class MocBugTest : public QObject
{
  Q_OBJECT
  public:
  MocBugTest()
  {
    const char* testMinimal = R"(a"//a
    )";
    const char* testRealWorld = R"(<?xml version="1.0" encoding="UTF-8"?>
      <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    )";
  }
};

      I get the message: 

      MocBugTest.h(0): Note: No relevant classes found. No output generated.

      It seems that MOC gets confused by the string constant containing a ", a // and a line break.

      I have added a minimal example and a real-world example. (I'd like the file to contain a hard-coded XSD.)
