Without storing the geometry, the call
  const JacobianTransposed& jacT = eIt->geometry().jacobianTransposed()
effectively resulted in an all-zero matrix, once optimization >=-O1 is
turned on.

This is very disturbing, since such code might be in quite some places.
We have to investigate this thoroughly.
