If qemu_find_file() doesn't find the BIOS it returns NULL; we were passing that unchecked through to load_elf(), which assumes a non-NULL pointer and may misbehave. In practice it fails with a weird message: $ qemu-system-ppc -M ppce500 -display none -kernel nonesuch Bad address qemu-system-ppc: could not load firmware '(null)' Handle the failure case better: $ qemu-system-ppc -M ppce500 -display none -kernel nonesuch qemu-system-ppc: could not find firmware/kernel file 'nonesuch' Spotted by Coverity (CID 1238954).
