<p>The symbols demangled is "(anonymous namespace)::{lambda()#1}::operator()() const::qstring_literal", thus this is the "static const QStaticStringData<Size> qstring_literal" from the QStringLiteral macro code about which it seems to complain being defined 3x. Though this is in a lambda, which should be instantiated each time when used, no? how could we clash here...<br />
[15:48] <volker|office> the symbol is not including the template arguments, but might be created per instantiation of  the template<br />
[15:49] <volker|office> it's the same content in all cases, so either the compiler merges them, or it needs to give them a unique name</p>

<p>Seems we need to work-around by not using the QStringLiteral here, and have to pass things explicitly for now.</p>
