Description
In a fresh Sage:
sage: var('a b c c0 c1 c2 c3 c4 c5 c6 d i j m n p r k u x y z') (a, b, c, c0, c1, c2, c3, c4, c5, c6, d, i, j, m, n, p, r, k, u, x, y, z) sage: a.series(x) 1*x + Order(x^20) sage: b.series(x) (b) sage: var('z0 z') (z0, z) sage: z0.series(x) 1*x + Order(x^20) sage: z.series(x) (z) sage: var('z0 z') (z0, z) sage: z.series(x) 1*x + Order(x^20) sage: z0.series(x) (z0)
It seems to always affect the first call to series.

Just add a doctest, and I will set a positive review.

- Commit set to 92e6f44e34dfa5e3a8bd68fb90bda06787362bdb
- Status changed from new to needs_review
- Summary changed from Bug with first call to ex.series() to Doctest: bug with first call to ex.series()
Note: The failure is dependent on memory content and changes with every change of the comment part of the code. So, while this is fixed and the test always passes the test might not fail in versions that have the bug reintroduced.

It's hard to have tests that are guaranteed to fail if a bug was (re)introduced, so we will just have to do the best we can.
