It's supposed to return sqrt(2)/pi. I get the result you post in master,
and the correct result in my new branch gruntz.
I take it you still get nan in the new branch? :/

No, that was on master.
What's the incantation to pull your branch? Do I need
Just do
git checkout -b test master
git pull https://github.com/ness01/sympy gruntz
[btw the correct answer is 2/sqrt(pi), contrary to what I said before.
In any case, definitely not nan.]

It passes here, now (the error_functions suite). I'll check your two
expressions, though.

Here, the two expressions give:
gruntz(gamma(x+1)/sqrt(2*pi)- exp(-x)*(x**(x+S(1)/2) +
... x**(x-S(1)/2)/12), x, oo)
oo
gruntz(exp(x)*exp(x**2)*(erf(x+1/exp(x))-erf(x)), x, oo)

Do you get oo, nan in master?

Okay, I wasn't aware that that URL would work.

Thanks for your help sorting this out.

This must be because of the pull request by raulb I pushed. I would be
happy to debug this, but since I cannot reproduce it this is somewhat
hard. It would be very helpful if you could post the output of the
failing test produced with SYMPY_DEBUG=True. The problem with this is
that the output
