Bug 156166

Description of problem:
Trying to run any (that I've tested) binary compiled for i386 causes a segmentation fault on x86_64 machine.  ldd does not work, nor am I able to generate core files from the seg fault - when 'ulimit -c' is increased, there is a kernel oops when trying to write out the core file.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Compile program on i386 (or use Fedora's firefox.i386 rpm for example)
2. Run binary
3.
  

Actual Results:  Segmentation Fault.

Expected Results:  Program should run as normal.

Additional info:

For example, I have compiled a simple 'hello world' program on i386 machine (forsberg):
[jeff@forsberg testcode]$ cat hello.c
#include <stdio.h>

main() {
    printf("Hi there.\n");
}
[jeff@forsberg testcode]$ gcc hello.c -o hello
[jeff@forsberg testcode]$ ./hello
Hi there.
[jeff@forsberg testcode]$ ldd hello
        libc.so.6 => /lib/libc.so.6 (0x00759000)
        /lib/ld-linux.so.2 (0x0073c000)

Running the same program on an Intel x86_64 machine (hell) causes a segfault:
[jeff@hell testcode]$ ./hello
Segmentation fault
[jeff@hell testcode]$ ldd hello
/usr/bin/ldd: line 116:  5447 Segmentation fault      LD_TRACE_LOADED_OBJECTS=1 LD_WARN= LD_BIND_NOW= LD_LIBRARY_VERSION=$verify_out LD_VERBOSE= "$@"
[jeff@hell ~]$ ulimit -c unlimited
[jeff@hell testcode]$ ./hello
Segmentation fault

This effects multiple fedora RPMs including firefox, for example.

I will attach dmesg output showing crashes for both firefox and above 'hello' example.
