Nope, the first wrong printing is the the first one inside
fmpq_set_fmpz_poly.
The first "print x" command at the Sage level corresponds to "x^8 + 2*x^7
+ 3*x^6 + 92233...".
> But the fmpz coefficients are the same, so it is (seemingly) the entries
in flint's global mpz array that are being zeroed when they shouldn't.
I'm not sure they really get zeroed.
Ok it sounds fishy, but I'm able to print again f correctly after having
done f.change_ring(QQ)...
I'll give the same piece of code a shot on Linux to see if anything looks
different but I doubt it, then I'll try to watch the addresses with gdb.
