The user provided a bug report about a segfault in qemu-riscv64-static when running a specific test from Cockatrice. The backtrace points to code_gen_buffer in QEMU's TCG (Tiny Code Generator) part. The regression was introduced by a specific commit, and even the latest QEMU HEAD has the issue. + +Looking at the backtrace, the crash happens in cpu_tb_exec, which is part of the TCG execution. The instruction at 0x7fffe849f133 is movzwl 0x0(%r13),%r13d. The address here is 0x0(%r13), which would be dereferencing r13 as a pointer. If r13 is zero or invalid here, that would cause a segfault. + +The code in the disassembly shows that r13 is being used as a pointer to load a word, then manipulated. The issue might be an invalid memory access due to incorrect code generation by TCG. Since TCG is responsible for translating guest instructions to host instructions, a bug here could generate an invalid host instruction that accesses incorrect memory, leading to a segfault. + +The categories given are instruction, syscall, or runtime. Since the problem seems to stem from incorrect host code generation (a faulty instruction generated by TCG that causes a segfault), this would fall under the 'instruction' category. It's not a syscall error, and while it's a runtime issue, the root cause is an incorrect instruction generated by QEMU's translator. +</think> + +instruction \ No newline at end of file |
