Segfault when take a ready snapshot

[m4p1e]

I have tried following ways

LD_PRELOAD=xxx/libs2e-x86_64.so xxx/qemu-system-x86_64 -enable-kvm  \
-drive if=ide,index=0,file=./image.raw.s2e,format=s2e,cache=writeback \
-serial file:./serial2.txt -enable-serial-commands \
-net none -net nic,model=e1000 \
-m 512M \
-nographic -monitor null

and

LD_PRELOAD=xxx/libs2e-x86_64.so xxx/qemu-system-x86_64 -enable-kvm  \
-drive if=ide,index=0,file=./image.raw.s2e,format=s2e,cache=writeback \
-serial file:./serial2.txt  \
-net none -net nic,model=e1000 \
-m 512M \
-nographic

and type savevm ready in qemu console. But they both show segfaults. It can be solved by modifying the snapshot name i.e., change ready to ready.ready. The image (ubuntu 22.04) is downloaded from our links.
