My question is: why was the buffer not set already? Do we have an
idea of where this MathData object was created?

In MathData::collectParameters (882ff.):

MathAtom & cell = operator[](pos);

Thanks, this is indeed what happens. I guess that the problem is that Inset::clone (and thus MathAtom::operator=') does not preserve the insets buffer.

I wonder whether at least the later should preserve it.
