The user reported that after upgrading QEMU from version 2.10.1 to 2.11.1 on their Gentoo host, they started encountering a segfault in qemu-arm when running Python and importing the portage module within a uclibc-ng chroot. They mentioned that other ARM chroots using glibc or musl don't have this issue, which is interesting. + +They also provided a backtrace from GDB showing where the segfault occurs. The trace indicates it's happening in `cpu_tb_exec` at `cpu-exec.c:167`. From what I know, QEMU uses TCG (Translation Cornucopia) for dynamic translation of guest code into host code. So any issues here could be related to how QEMU handles instruction execution or memory management. + +The user did some bisecting and found that a specific commit introduced the problem. They reverted a change related to `MAX_RESERVED_VA` from 0x77000000 to a different value, which fixed the issue for them. I'm not entirely sure what `MAX_RESERVED_VA` does, but it sounds like it's related to memory reservation or address space management in QEMU. + +Looking at the possible categories: instruction, syscall, runtime. The bug seems to be happening during runtime because it occurs while executing code (specifically Python importing a module). It's not a faulty instruction per se, nor is it directly related to a system call. Instead, it's an issue that arises when QEMU is running and handling the guest's execution. + +So, considering all this, I think the category should be 'runtime'. +</think> + +The bug occurs during runtime when executing code in the uclibc-ng chroot, specifically within QEMU's TCG subsystem, leading to a segfault. This isn't an issue with an instruction or syscall but rather how QEMU handles execution. + +**Answer:** runtime \ No newline at end of file |
