- Status changed from new to needs_review
- Reviewers set to Karl-Dieter Crisman
- Milestone set to sage-duplicate/invalid/wontfix
And checking by hand works.
Since this was undoubtedly an XP machine on which the original failure was reported, I will move this to sage-invalid.

But doing anything other than the first one by hand doesn't work. In fact, nasty things happen.

I attempted this, but got forking errors; that doesn't mean it doesn't actually work. JP, want to give it a whirl?

And the test passes for me (64bits W7 + 5.6.rc0).

And the test passes for me (64bits W7 + 5.6.rc0).
Don't forget to try these by hand as well. In the past I've had failures only in the terminal.

comment:9 Changed 4 months ago by jpflori

No problems on another 32 bits W7, let's close this one.
