Apr 16, 2018 at 14:52 comment added Daniel Lichtblau I think the issue remaining in 11.3 is the same as noted here and also here. All three behave better in the current devel code and, barring trouble appearing in testing (which has not happened as yet) the fixes will appear in the next release.
Apr 15, 2018 at 20:43 comment added Daniel Lichtblau I'll take another look...
Apr 15, 2018 at 3:51 comment added bbgodfrey @DanielLichtblau The problem persists with Version 11.3.

Sep 29, 2017 at 20:44 comment added bbgodfrey @DanielLichtblau Please do. This looks like a bug to me, new to Version 11. However, I shall hold off adding a bug header until you have a chance to weigh in. Thanks.

Sep 29, 2017 at 20:22 comment added Daniel Lichtblau That (1 - x)^(-1) inside the coefficient list for ser2 looks suspect. Will investigate (next week).

Sep 29, 2017 at 19:09 comment added Stan Thanks for your reply. By the way, I just updated my original question with an additional example, in which the consequences are more subtle, but also harder to detect in a real-life setting.
