The user is experiencing a core dump when running an ARM 32-bit binary in QEMU's user mode, but when debugging with GDB, it exits normally. They mentioned that QEMU isn't correctly translating the BKPT instruction into a SIGTRAP signal. + +First, I need to recall what BKPT does. On ARM, BKPT is a breakpoint instruction that triggers a debug exception, which should be caught by the debugger or the emulator. In QEMU, when running in user mode, it should simulate this by sending a SIGTRAP signal to the guest program. + +The user provided the disassembly snippet with a BKPT instruction at address 0xa608. When the program hits BKPT, QEMU should handle it by generating a SIGTRAP. However, the issue is that QEMU isn't doing this correctly, leading to a core dump. But when using GDB to remote-debug, it works normally. That suggests that when GDB is attached, it's handling the BKPT properly, perhaps because GDB intercepts the SIGTRAP and manages it as a breakpoint, allowing the program to exit normally. + +The core dump is likely happening because the SIGTRAP isn't being handled correctly by QEMU. If the BKPT isn't converted into a SIGTRAP, the program might be in an unexpected state, leading to a crash. The user also mentioned a fixed bug related to this, but the problem persists, which could indicate a residual issue or a different underlying cause. + +Looking at the categories: instruction, syscall, runtime. The problem is directly related to the handling of the BKPT instruction. Since the instruction's behavior in QEMU is incorrect, it's an issue with the instruction emulation. The core dump arises because the instruction isn't being processed as expected, leading to an uncaught signal (SIGTRAP) or an invalid operation. Therefore, this should be classified under the 'instruction' category. +</think> + +instruction \ No newline at end of file |
