The user is reporting an issue with QEMU where running a 32-bit ARM binary causes a core dump, but when debugging with GDB, it exits normally. The problem seems to be related to the BKPT instruction not being properly converted into a SIGTRAP signal in QEMU's user mode. + +First, the user mentions that the BKPT instruction at address 0xa608 isn't recognized correctly. The BKPT instruction in ARM is used for breakpoints, and when executed, it should generate a SIGTRAP signal. In QEMU, the emulator is supposed to catch this instruction and translate it into the appropriate signal for the guest OS. If QEMU isn't handling this correctly, it could lead to unhandled exceptions, hence the core dump. + +Looking at the GDB session, when the user steps through the instructions, executing the BKPT instruction causes QEMU to loop indefinitely without sending the SIGTRAP. This suggests that QEMU's ARM emulator isn't detecting the BKPT opcode and triggering the signal handling mechanism. The backtrace from GDB shows that QEMU is hitting an unhandled CPU exception, leading to an abort. The error message "qemu: uncaught target signal 5 (Trace/breakpoint trap)" indicates that QEMU received a signal (SIGTRAP) but didn't handle it properly. + +The user also references a fixed bug (Launchpad 1873898), but the problem persists. That suggests either the fix isn't applied, or there's a different but related issue. Since the problem is directly tied to the handling of the BKPT instruction and the resulting signal, this falls under instruction handling. The core dump occurs because QEMU doesn't process the BKPT instruction correctly, leading to an unhandled exception. + +In the categories provided, 'instruction' is for faulty instruction handling, 'syscall' for system call issues, and 'runtime' for other runtime errors. Since the root cause is QEMU's incorrect handling of the BKPT instruction, the correct category is 'instruction'. +</think> + +instruction \ No newline at end of file |
