Description (last modified by )
Here is a short example found by Burcin and reproducing the bug:
b = [var('b_%s'%i) for i in range(4)] precomp = (2^b_2 + 2)*(2^b_1 + 2^(-b_1) + 2^b_1*2^b_0 - 2^b_1*2^(-b_0) - 2^(-b_1)*2^b_0 - 2^(-b_1)*2^(-b_0) + 2^b_0 + 2^(-b_0) - 9) + (2^b_1 + 2^(-b_1) + 2^b_1*2^b_0 - 2^b_1*2^(-b_0) - 2^(-b_1)*2^b_0 - 2^(-b_1)*2^(-b_0) + 2^b_0 + 2^(-b_0) - 9)/2^b_2 repl_dict = {b_0: b_0, b_3: b_1, b_2: b_3, b_1: b_2} P = precomp.substitute(repl_dict) P.expand()
