Infinite recursion in sympy 1.0

[Peter Wortmann]

Hi everyone,

sympy 1.0 has the problem that code like follows recurses indefinitely:

  from sympy import *
  b = Symbol("b")
  print(log(Max(b, b**2),2))

This problem exists pretty much exactly in 1.0, as the fix has in fact been around for quite some time (41eecbc, according to bisect). However, this basically makes sympy 1.0 unusable for our purposes. At this point it has become quite a bother to keep telling people to downgrade. Any advice?

Many thanks,
  Peter
