  • Description modified (diff)
  • Report Upstream changed from N/A to Not yet reported upstream; Will do shortly.

This is probably followup to #8775. Certainly it is a Ginac issue, isn't it? (We'll eventually want to confirm this and report upstream.)

This is probably followup to #8775.

Meaning that #8775 fixed the issue for basic functions, but apparently it doesn't propagate somehow to products.

  • Cc rbk added
  • Milestone set to sage-4.7.1
  • Priority changed from major to critical
  • Report Upstream changed from Not yet reported upstream; Will do shortly. to None of the above - read trac for reasoning.

I sent an email about this to ginac-devel. It didn't show up yet, so I can't link to the thread. I can include a fix in the next pynac release if there is a fix in the next couple of days.
