Description

Small bug in file qgsgeometryvertexindex.cpp (revision 4502), lines 31-34: QgsGeometryVertexIndex::operator= must return a value.

Current incomplete version:

[[QgsGeometryVertexIndex]]&
[[QgsGeometryVertexIndex]]::operator=(QgsGeometryVertexIndex const& rhs)
{
   mIndex = rhs.mIndex;
}

Possible min. required fix:

[[QgsGeometryVertexIndex]]&
[[QgsGeometryVertexIndex]]::operator=(QgsGeometryVertexIndex const& rhs)
{
   mIndex = rhs.mIndex;
   return *this
}

But I'm not sure what copy semantic is expected here.
What about self-copying?
Usually, self-copying is forbidden, then

[[QgsGeometryVertexIndex]]&
[[QgsGeometryVertexIndex]]::operator=(QgsGeometryVertexIndex
const& rhs)
{
   if (&rhs != this)
   {
      mIndex = rhs.mIndex;
   }
   return *this
}
