The recently introduced feature that allows 32 bit guests to be executed under KVM on a 64-bit host incorrectly handles the case where more than 1 cpu is specified using '-smp N' For instance, this invocation of qemu qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2 produces the following error qemu-system-aarch64: Expected key=value format, found aarch64 which is caused by the destructive parsing performed by cpu_common_parse_features(), resulting in subsequent attempts to parse the CPU option string (for each additional CPU) to fail. So duplicate the string before parsing it, and free it directly afterwards.
