環(huán)境：
操作系統(tǒng)：Red Hat Enterprise Linux Advanced Server 4(kernel 2.6.9-42.ELsmp)
數(shù)據(jù)庫：Oracle9i Enterprise Edition Release 9.2.0.1.0
gcc: 3.4.6 20060404 (Red Hat 3.4.6-3)
libc: libc-2.3.4.so
軟件：FreeRADIUS Version 1.1.7
現(xiàn)象：
當(dāng)freeradius使用oracle(使用mysql時沒有此問題)，并且配置正確成功連接上后，在按Ctrl+C退出時會coredump。當(dāng)配置不正確沒有連上數(shù)據(jù)庫時按Ctrl+C退出時不會coredump。不知道是什么原因？
core文件里看不到出問題的地方。有沒有什么辦法找出原因？我在程序中加打印，在main()中到exit()時都正常。
