The user is having an issue where their program runs fine under GDB but crashes when run directly in QEMU. Specifically, they're getting a core dump because of a signal 5 (Trace/Breakpoint trap). + +Looking at the disassembly, there's a BKPT instruction at address 0xa608. I remember that BKPT is used for breakpoints and should generate a SIGTRAP when hit. But in QEMU's Linux-user mode for ARM 32-bit, this isn't handled correctly. The user mentioned they found a bug report indicating this was fixed, but it's still happening. + +They provided the GDB session where stepping through the code lands on the BKPT instruction without crashing. However, when running outside of GDB, QEMU doesn't recognize the BKPT and triggers a SIGTRAP, leading to a core dump. + +The backtrace shows that QEMU is processing pending signals, specifically signal 5 (SIGTRAP), which causes it to abort. This suggests that the issue lies in how QEMU handles the BKPT instruction when not under GDB's control. + +So, this seems like an issue with how instructions are handled by QEMU—specifically, the BKPT instruction isn't being translated into a SIGTRAP correctly in non-debugging scenarios. +</think> + +The problem arises because QEMU doesn't properly convert the BKPT instruction into a SIGTRAP signal when not debugging.
