第一步：找到core file是由哪個程序產生的

[[email protected] dennis]# file core.11751

core.11751: ELF 64-bit LSB core file AMD x86-64, version 1 (SYSV), SVR4-style, from ‘Java‘

[[email protected] dennis]#

從上面可以看出，該core file是由java產生的。

第二步：用gdb

[[email protected] dennis]# gdb Java core.11751

#0 0x00002b08894f4215 in raise () from /lib64/libc.so.6

然後執行bt命令

(gdb) bt

(gdb)

從上面bt命令獲取到的堆棧信息來看，可以清晰地看到問題所在的源代碼的行數，即：

hc_decoder.c:2517

這樣就便於分析和定位問題。
