Description of problem:
I was testing a few things from rawhide, and had to install a new glibc.  Later when I compiled some code, I found that strcmp() crashes with two valid strings as input.  That happened only in 64 bit mode, but later I found that strlen() has the same problem, both in 64 and 32 bit mode.

Version-Release number of selected component (if applicable):
gcc-4.4.1-2.fc11.x86_64
glibc-2.10.90-23.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Create this program
#include <string.h>
#include <stdio.h>

char *s1 = "String";

int main()
{
  fprintf(stderr, "Computing length of \"%s\"\n", s1);
  int len = strlen(s1);
  fprintf(stderr, "Length is %d\n", len);
  return 0;
}

2. Compile with: cc c.c -o c
3. Run: ./c
  
Actual results:
[göran@mimmi ~]$ ./c
Computing length of "String"
Segmentation fault

Additional info:
I of course realise this might not be a supported combination (whatever that would mean when it comes to rawhide).  But I was still surprised to see it and wanted to mention it.  I don't have any system I can upgrade completely to rawhide right now.

If this isn't supposed to work, maybe it would be worth a "Conflict: gcc < <whatever>" in the glibc rpm?

I tried to install the glibc-debuginfo rpm and look at what actually happens.  But then my debugger started to crash too! (gdb-6.8.50.20090302-23.fc11.x86_64)
