The user reported that after upgrading QEMU from 2.10.1 to 2.11.1 on a Gentoo host, their uclibc-ng chroot environment started segfaulting when running Python and importing the portage module using qemu-arm in user mode. + +They provided a backtrace showing where the segmentation fault occurs. The trace starts at `cpu_tb_exec` in `cpu-exec.c`, which is part of QEMU's TCG (Translation-Caching-Generator) acceleration. The error happens during code generation or execution within the emulator, not involving any hardware devices or system-level operations. + +The user also mentioned that other chroots with glibc and musl don't have this issue, so it seems specific to uclibc-ng. They bisected QEMU and found a commit related to `MAX_RESERVED_VA` which they reverted to fix the problem. This suggests it's an issue within how QEMU handles memory or code generation for ARM in user mode. + +Since the problem occurs when running user-space programs (like Python) inside the chroot using qemu-arm, and not when dealing with system-level operations like device emulation or higher privileges, this points towards a user-mode issue. The bug affects the execution of applications within the emulated environment without involving QEMU's system-mode features such as virtual devices or kernels. + +Therefore, it's likely a user-mode related problem. +</think> + +user \ No newline at end of file |
