Question

当运行从（centos 5）生成的共享二进制文件时，我处于浮点异常中（在Linux ubuntu-610 2.6.17-10-generic＃2 SMP Tue Dec 5 5 21:16:35 UTC 2006 x86_64 GNU / Linux中）。2.6.18-398.el5＃1 SMP Tue Sep 16 20:50:52 EDT 2014 x86_64 x8n6_64 x86_64 GNU / Linux）
但是静态二进制文件可以运行。

我遇到什么问题？ 是否可以解决这种情况？无需在Linux中构建二进制文件ubuntu-610 2.6.17-10-generic＃2 SMP Tue Dec 5 21:16:35 UTC 2006 x86_64 GNU / Linux。

浮点异常

活着

**静态链接：没问题

** gdb tracking

执行共享二进制文件时出现浮点异常，但可以运行静态链接二进制文件
