Let's break down the information given. + +The issue occurs when running an ARM program under QEMU. The error message mentions "elfload.c:2294: probe_guest_base: Assertion `have_guest_base' failed." That suggests something is wrong during the loading of the guest executable, specifically when probing for the guest base address. + +Looking at how it's run: the user is using the arm-linux-user binary from QEMU. The term "user" here usually refers to user-mode emulation, which means QEMU is emulating an ARM CPU but running in a way that allows it to execute ARM binaries directly without booting a full OS. This mode typically doesn't require virtualized peripherals or higher privileges because it's more about translating the binary for execution. + +The program being run is a simple C program compiled with arm-linux-gnueabi-gcc, which targets the Linux userland (hence the 'linux-user' in the QEMU path). It doesn't need any special OS-level features beyond what's provided by the host's dynamic linker or libraries. So this isn't about booting an OS image but executing a compiled binary. + +The fact that it worked in QEMU v5.0.0 but fails in the master branch points to a regression in user-mode handling between versions. The error during elfload suggests something changed in how QEMU loads or sets up the guest environment, possibly related to memory layout or base address probing. + +Since the problem arises when running an ARM binary directly without any OS or device emulation beyond what's needed for the program to execute, this is definitely a user-mode issue. If it were system-mode, we'd be talking about emulating a full system with devices, booting kernels, etc., but that's not the case here. + +So putting it all together: the bug affects user-mode emulation because it's related to executing an ARM binary directly and failing during the setup phase specific to that mode. There's no mention of peripherals, higher privileges beyond what user-mode uses, or OS-level tasks other than running a program. +</think> + +user \ No newline at end of file |
