我正在尝试为两个不同的Linux环境构建一个简单的C程序。在一个设备上，程序运行正常，在另一设备上，程序生成浮点异常。该程序除了从main返回0之外什么都不做，这使我相信与启动代码也许不兼容，也许是ABI？
该程序使用gcc编译，具有以下构建规范：
使用内置规格。目标：i386-redhat-linux配置为：../configure --prefix = / usr --mandir = / usr / share / man --infodir = / usr / share / info --enable-shared --enable-threads = posix --enable-checking = release --with-system-zlib --enable -__ cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages = c，c ++，objc，obj-c ++ ，java，fortran，ada --enable-java-awt = gtk --disable-dssi --disable-plugin --with-java-home = / usr / lib / jvm / java-1.4.2-gcj-1.4。 2.0 / jre --with-cpu = generic --host = i386-redhat-linux线程模型：posix gcc版本4.1.2 20080704（Red Hat 4.1.2-52）
程序源如下：
int main()
{
return(0);
}
在Celeron设备上，此程序在GDB下生成以下内容：
[root@n00200C30AA2F jrn]# /jrn/gdb fail GNU gdb Red Hat Linux (5.3post-0.20021129.18rh) (gdb) run Starting program: /jrn/fail

以下是我可以考虑收集的详细信息，以帮助您发现正在发生的事情：

我该怎么做才能确定导致此问题的原因？尝试静态链接到某个版本的libc怎么样？
在GDB下发生故障后，我执行：
(gdb) x/1i $eip
0x40001cce: divl 0x164(%ecx)
(gdb) info reg
eax 0x6c994f 7117135
ecx 0x40012858 1073817688
edx 0x0 0
ebx 0x40012680 1073817216
esp 0xbffff740 0xbffff740
ebp 0xbffff898 0xbffff898
esi 0x8049580 134518144
edi 0x400125cc 1073817036
eip 0x40001cce 0x40001cce
eflags 0x10246 66118
cs 0x73 115
ss 0x7b 123
ds 0x7b 123
es 0x7b 123
fs 0x0 0
gs 0x0 0
(gdb) x/1wx 0x164+$ecx
0x400129bc: 0x00000000
(gdb)
根据我收到的帮助，看来由于某种原因，libc启动代码被除以0。
现在的问题是，是什么导致这种明显的不良行为？某些东西一定与其他东西不兼容吗？
