Revert 3b5a45c6ab92 The speedup fix in 3b5a45c6ab92 contains some sort of bug related to operand manipulation during expression simplification or copying. This leads to crashes that so have have eluded tracing. Revert back to known working version of the code, even though slower, to avoid regressions.
