我希望有人可以幫我除錯 apache2 錯誤。由於某些原因，我最近在我的一個系統上遇到了很多錯誤：
Sat Oct 10 16:49:24.101959 2015] [core:notice] [pid 18380] AH00051: child pid 2126 exit signal Bus error (7), possible coredump in /tmp/apache-coredumps
[Sat Oct 10 16:50:35.178108 2015] [core:notice] [pid 18380] AH00051: child pid 1971 exit signal Bus error (7), possible coredump in /tmp/apache-coredumps
[Sat Oct 10 16:50:43.188837 2015] [core:notice] [pid 18380] AH00051: child pid 2413 exit signal Bus error (7), possible coredump in /tmp/apache-coredumps
我嘗試使用 gdb 進行調試，但在讓 gdp 釋放我的 coredump 後我不知道如何繼續。這是 gdb 輸出：
