I'm having some trouble fixing this. I've pushed what I've done so far to
my no-evalf-1 branch. But there is a problem with a test in

Never mind, I figured it out. I just needed to change round(1) to round(2)
in __int__. Still, I would appreciate a review.

OK, see https://github.com/sympy/sympy/pull/1501. I'm not feeling

I get a useable stacktrace, for the record. Time to switch to Linux? ;-)
In any case, the problem is that sympy calls
sage.libs.mpmath.ext_libmp.mpf_log with prec=1,

Anyway, this has pointed me in the right direction. It has something to do

Ah, well it's the simple fact that it's using Sage's mpf_log instead of the

n(1) and evalf(1).

mpmath internally has different backends to do the computation. It uses
mpir/mpfr if possible (i.e. if used from within Sage) and falls back to
some python code

Did you try sage -gdb and then bt (backtrace) after the crash?

I've narrowed it down to (1/log(pi)).is_nonnegative. I can't figure out
where the code is going from there, though.
