POSIX SIGBUS的可能原因是什么？ [英] What are the possible reasons for POSIX SIGBUS?

问题描述

我的程序最近使用下列堆栈崩溃：

My program recently crashed with following stack;

Program terminated with signal 7, Bus error.
#0  0x00007f0f323beb55 in raise () from /lib64/libc.so.6
(gdb) bt
#0  0x00007f0f323beb55 in raise () from /lib64/libc.so.6
#1  0x00007f0f35f8042e in skgesigOSCrash () from /usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1
#2  0x00007f0f36222ca9 in kpeDbgSignalHandler () from /usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1
#3  0x00007f0f35f8063e in skgesig_sigactionHandler () from /usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1
#4  <signal handler called>

有人能告诉我应该检查我的代码以避免这种情况吗？

Could someone tell me what should i check in my code to avoid this? or is this something oracle should fix?

Main reasons you could get BUS error revolves around inaccessible memory. This could be due to many reasons:-

• 通过已删除的指针访问。


• 通过未初始化指针。


• 通过NULL指针访问。


• 访问不是您的地址。可能是由于溢出错误。

• Accessing through deleted pointer.
• Accessing through uninitialized pointer.
• Accessing through NULL pointer.
• Accessing the address which is not yours. could be due to overflow errors.
