* upstream: N/A => Reported upstream. Little or no feedback.
Comment:
I've reported it upstream as this is clearly a Pari bug:
{{{
? issquarefree(0)
*** at top-level: issquarefree(0)
*** ^---------------
*** issquarefree: zero argument in an arithmetic function.
*** Break loop: type 'break' to go back to GP
}}}
In older Pari versions we do get 0 as output.
