HelloWorld.c CRASHES when moved from FC6 to FC3!!

[troubled_gcc_user]

I wrote this little program hello.c and compiled it on Fedora Core
6. It gives a Floating Point Error on Fedora Core 3. What is going on
here????????

My problem, obviously, lies with a larger app that I compile on FC6
and want to run on FC3, this example is just an illustration of the
problem. I am desperate. I need to solve this shit. 

See output here:

FC6:~/tmp ==>cat hello.c
#include <stdio.h>
#include <stdlib.h>

int main( int argtc, char * argv[] ) {

  printf( "Hello\n" );

  exit( 0 );
}
FC6:~/tmp ==>gcc -o hello hello.c 
FC6:~/tmp ==>./hello 
Hello

@@@@@ Then I move it to a Fedora Core 3 machine and run it:

FC3: ==>./hello 
Floating point exception (core dumped)

FC3: ==>strace ./hello 
execve("./hello", ["./hello"], [/* 63 vars */]) = 0
brk(0)                                  = 0x85ff000
