The user mentioned that when they upgraded GCC from version 4.8.3 to 4.9.0, running commands like rpm caused QEMU to segfault. They tried rebuilding QEMU with GCC 4.9.0 and even used different sources, but the issue persists. + +First, I need to understand what's causing the segfault. The user is using QEMU's ARM emulator (qemu-arm). Segmentation faults usually happen when there's an invalid memory access. Since this started after upgrading GCC, it might be related to how code is being compiled or optimized. + +Looking at the categories provided: mistranslation, assembly lowering, and others like device, network, etc. Mistranslation refers to incorrect mapping from source architecture to target, which could happen in user-mode. Assembly lowering is about converting high-level IR to machine code. + +The fact that GCC 4.9.0 is involved suggests it's related to how the compiler generates code that QEMU then emulates. If QEMU relies on certain optimizations or specific assembly instructions that GCC 4.9.0 doesn't generate correctly for ARM, that could cause a segfault during execution. + +Another angle is whether this is a problem with the way QEMU handles signals or exceptions. Maybe the new GCC compiler produces code that triggers an unhandled signal in QEMU's emulation environment. + +Considering the options: since it's about incorrect mapping and possibly assembly generation, "mistranslation" or "assembly lowering" seem relevant. However, the issue arises when using a specific GCC version, which affects how binaries are generated. This might be more related to how QEMU interprets those binaries rather than its own translation. + +Wait, but the user is running an ARM chroot with QEMU as the interpreter for binfmt_misc. So if the GCC 4.9.0 generates code that's not handled correctly by QEMU's ARM emulator, it could cause a segfault when executing those binaries (like rpm). + +So, this might be related to how QEMU translates ARM code to run on the host system. If there's an issue with how certain instructions or optimizations are handled in the translation process, especially under GCC 4.9.0, that would fall under mistranslation. + +Alternatively, it could be an assembly lowering issue if QEMU's own assembly generation for the target is flawed when dealing with code compiled by GCC 4.9.0. + +But given that it's about binary compatibility and how QEMU emulates binaries generated by a specific compiler version, "mistranslation" seems more accurate as it directly relates to the semantic mapping from source (the ARM binary) to execution on the host. +</think> + +The bug report involves a segfault in QEMU when using GCC 4.9.0, suggesting an issue with how binaries are translated or executed under specific compiler conditions. + +**Answer:** + +mistranslation \ No newline at end of file |
