Let's look at the information provided. + +The issue occurs when using dh_fixperms, which runs a find and xargs chmod. That sounds like it's happening during package installation or build processes, so maybe within the user space of an application. + +Then there's debootstrap --second-stage, which is used to set up a chroot environment for arm64 on a non-native host. It's invoking shell scripts like postinst, which are part of Debian packages and typically run in the user mode context. + +Looking at the stack trace from gdb, the crash happens in memcpy while handling signal processing. The function calls go through target_setup_sigframe, setup_frame, process_pending_signals, and cpu_loop in main.c. These functions seem to be dealing with signals and CPU loops within QEMU's user-mode emulation. + +The problem was fixed by sigprocmask wrapper patches from SUSE's tree. Since these are wrappers related to signal handling in the user space, it points towards user-mode issues where QEMU is emulating a target architecture's userspace processes. + +Qemu-system typically runs as system-mode, dealing with hardware and full OS emulation, but qemu-aarch64-static is a user-mode binary meant for executing ARM64 binaries on an x86 host. The crash during signal handling aligns more with the user-mode context rather than managing devices or peripherals in system-mode. + +So putting it all together, this bug is related to user-mode emulation within QEMU. +</think> + +user \ No newline at end of file |
