森です。 先のプログラムを実行して、一回 telnetして Control-C が効かなくなった 状態のプロセスに gdbで attachしました。 デバッガを使ったことが無かったので何か間違えてたらすみません。 (gdb) bt #0 0x281a1900 in __sys_poll () from /usr/lib/libc_r.so.4 #1 0x281a0e4c in _thread_kern_sched_state_unlock () from /usr/lib/libc_r.so.4 #2 0x281a0811 in _thread_kern_scheduler () from /usr/lib/libc_r.so.4 #3 0x0 in ??
