gcc compiled executable not working across x86_64 linux platforms
Hi
I compiled a hello world program on two different 64-bit Linux machines, named quimby and node0331. When I compile on quimby and run on node0331 I get a "Floating exception (core dumped)" error. But if I do it in reverse, things work fine.
Here's my compilation on quimby:
$ uname -a
Linux quimby 2.6.18-8.1.15.el5 #1 SMP Mon Oct 22 08:32:28 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux
$ cat hello.c
#include <stdio.h>
int main()
{
printf("Hello World\n");
return 0;
}
$ gcc -c hello.c -o hello.o ;
$ gcc -o hello hello.o
$ ./hello
Hello World
The I go to node0331 and run there:
$ uname -a
Linux node0331 2.6.9-42.0.3.ELsmp #1 SMP Fri Oct 6 06:28:26 CDT 2006 x86_64 x86_64 x86_64 GNU/Linux
$ ./hello
Floating exception (core dumped)
But again if I do this in reverse, things work fine. Has anyone ever experienced this problem.
Thanks in advance,
Sam

isalist(1) User Commands isalist(1)
NAME
isalist - display the native instruction sets executable on this platform
SYNOPSIS
isalist
DESCRIPTION
isalist prints the names of the native instruction sets executable on this platform on the standard output, as returned by the SI_ISALIST
command of sysinfo(2).
The names are space-separated and are ordered in the sense of best performance. That is, earlier-named instruction sets may contain more
instructions than later-named instruction sets; a program that is compiled for an earlier-named instruction sets will most likely run
faster on this machine than the same program compiled for a later-named instruction set.
Programs compiled for instruction sets that do not appear in the list will most likely experience performance degradation or not run at all
on this machine.
The instruction set names known to the system are listed in isalist(5). These names may or may not match predefined names or compiler
options in the C language compilation system,
