Never mind. I just found Martin Simmons fixed the same issue.

QEMU should convert signal number reciving from GDB cilent from gdb-signal number to target sginal number - using gdb_signal_to_target(). In this case, GDB_SIG_BUS is 10. However, 10 is SIGUSR1 for target. So QEMU continues with the wrong signal number. #include <stdio.h> #include <signal.h> void handle_signal (int sig) { puts ("Hello"); } int main () { signal (SIGBUS, handle_signal); kill (0, SIGBUS); return 0; } (gdb) target remote :25566 Remote debugging using :25566 0x00008b98 in _start () (gdb) c Continuing. Program received signal SIGBUS, Bus error. 0x0000e18c in kill () (gdb) c Continuing. Program terminated with signal SIGUSR1, User defined signal 1. ^^^^^^^ The program no longer exists.
