This is super odd. Can you reproduce it inside GDB and get a "bt full" of the 
crashed thread please? Maybe the bug is in Cpp::ReferenceCountedStringSet - 
hm. Also try to output the string that is tried to be added in 
CppPreprocessEnvironment::merge, i.e. something like

const auto str = it.ref();
qDebug() << str.index(); // will this crash already?
qDebug() << str; // or this?
m_macroNameSet.insert(str);


Thanks
