Comment (by cwitty):
I certainly don't think the ticket is invalid; it's definitely a bug in
Sage (via Pari), even if it's not a bug in the Sage library code.
For this example, it presumably works to divide through by the leading
coefficient (to get a monic polynomial) before handing off to Pari. Maybe
that's a reasonable strategy in general?
Or, we could just report it as a bug to Pari upstream, and hope they fix
it.
