corrupted siqs.dat leads to segmentation fault #61
Description
to reproduce:
rm factor.log factor.json session.log
printf 'N 0x80000000000000000000000000000046800000000000000000000000000008f7\nA 0x7f343be8fb6fd65a69d2bde39e49\nR 163ef 1 2c 4e 5f d7 1cd 2662 5500 7344 L 1 8525cb\nR 29c2d 1 31 3c 4f f3 42d c08 3941 77a7 L 1 141f49\nR 30cd6 1 57 78 79 132 2e4' > siqs.dat
echo 'factor(3351951982485649274893506249551461534627981888895711889290423167940493974710190013582638075598280156206200387201406946734092392938070873150538883477422699)' | yafu
such a corrupted siqs.dat may be caused by yafu being uncleanly killed, for example
N=3351951982485649274893506249551461534627981888895711889290423167940493974710190013582638075598280156206200387201406946734092392938070873150538883477422699
rm factor.log factor.json session.log siqs.dat
echo "factor($N)" | timeout -s9 30s yafu # kill it in the middle of siqs (on my machine 30s is sufficient)
echo "factor($N)" | yafu # this one will load siqs.dat and segmentation fault
