Yeah, we shouldn't dump core even if the guest binary is doing weird stuff... > Running a aarch64-softmmu QEMU built from today's master, I get > > $ qemu-system-aarch64 -M virt -nographic -cpu cortex-a53 -bios QEMU_EFI.fd > Bad ram pointer 0x54 > Aborted (core dumped) > > UEFI build is here > http://people.linaro.org/~ard.biesheuvel/QEMU_EFI.fd.xz Thanks for the bug report -- I have reproduced it and will have a look. This bug is also present in QEMU 2.6, so this isn't a recent regression and likely not a blocker for 2.7 release (unless the bug turns out to have a simple fix and be of the "how did this ever work" flavour ;-)) thanks -- PMM
