Hi,
When i try to do some test sieving using guideline suggested in
README.nonlinear,
i've tried imported the polynomial, works well sieving until about 70%
then this error appear:

Error:Lattice Sieving: Program run on localhost failed with exit code 1

can disable this check with the -allow-largesq argument,\n       It is

Have tried once more and happens to be the same error.
Thank you.
