See attachment for files to reproduce the issue. (Moc output can be edited manually to fix its errors.)

Example of the input, output, and fix:

input: Q_PROPERTY(Prop & prop READ prop WRITE setProp)
alt: Q_PROPERTY(Prop %AMPERSAND% prop READ prop WRITE setProp)

output1: reinterpret_cast< Prop&>(_v) = prop();
alt: %STAR% reinterpret_cast< Prop %AMPERSAND% %STAR%>(_v) = prop();

fix1: reinterpret_cast< Prop*>(_v) = &prop();
alt: %STAR% reinterpret_cast< Prop %STAR% %STAR%>(_v) = %AMPERSAND% prop();

output2: setProp(reinterpret_cast< Prop&>(_v));
alt: setProp(%STAR% reinterpret_cast< Prop %AMPERSAND% %STAR%>(_v));

fix2: setProp(*reinterpret_cast< Prop*>(_v));
alt: setProp(%STAR% %STAR% reinterpret_cast< Prop %STAR% %STAR%>(_v));
