nfsubfields() bug


Hi,

? p=x^10 - 386*x^9 + 57634*x^8 - 1013722*x^7 + 5519009*x^6 - 6234928*x^5 + 4790609*x^4 + 376538*x^3 + 65170*x^2 + 82*x + 1;
? nfsubfields(nfinit(p),5)
[]
? nfsubfields(nfinit(polredabs(p)),5)
[[x^5 - 7*x^4 + 63*x^3 - 301*x^2 + 1080*x - 900, -x^2 + 1]]

This bug has existed forever.

Thanks

Igor
