No crash here, what is your base commit?

./qemu-system-x86_64
qemu-system-x86_64: No machine specified, and there is no default
Use -machine help to list supported machines
$ ./qemu-system-x86_64 -M help
Supported machines are:
microvm              microvm (i386)
none                 empty machine
