Thanks Barton. I've made the bug report. In the meantime, I took a
look in the source code, which I think told me what I wanted to know.
Just to check: when to_poly_solve says "Assuming that expr # 0", does
the "#" mean "not equal to"?
Something else that arose from the source code... the comments therein
suggest that to_poly(expr,var) is only intended to produce a
polynomial with roots at the same values of var as expr, not a
polynomial that's exactly the same everywhere as expr. So does this
mean that when I run to_poly_solve(equation,var), I need to make sure
equation has zero on one side?
