The problem involves a segmentation fault when using QEMU in armeb mode (which is big-endian). The issue seems to be with the VDSO method for __clock_gettime64(). + +The user provided details about rebuilding glibc with VDSO disabled, which fixed the problem. They also included a stack trace showing that the crash occurs in clock_gettime.c at line 42, where it's making an internal vsyscall to vdso_time64. + +From my understanding, VDSO (Virtual Dynamic Shared Object) is part of user-mode because it's a shared object used by user-space applications. QEMU's system emulation would handle the kernel and hardware parts, but since this issue is about a specific library call crashing in user space, it might be related to how QEMU emulates certain syscalls or handles memory for big-endian systems. + +The fact that the problem doesn't occur on qemu-arm (little endian) suggests it's an emulation issue specific to armeb. Maybe there's a bug in how QEMU handles the VDSO for big-endian targets, leading to incorrect addressing or alignment when accessing memory during the vdso_time64 call. + +Since the crash is happening within user-space code (glibc), and not at the kernel level, this seems more like a problem with the user-mode emulation provided by QEMU. Therefore, it's likely a user-mode related issue. +</think> + +user
