Missing strlen_sse4.S results in Segmentation Fault

i'm writing a small tool written in c and met on a segmentation fault which i don't know currently how to resolve. Running in GDB gives me the following hint:

    Program received signal SIGSEGV, Segmentation fault. 
    __strlen_sse42 () at ../sysdeps/x86_64/multiarch/strlen-sse4.S:32 
    ../sysdeps/x86_64/multiarch/strlen-sse4.S: File or Directory not found 
    in ../sysdeps/x86_64/multiarch/strlen-sse4.S
    (gdb) bt

I would say: i'm missing a specific dependency on my system or in my executable (Ubuntu 11.04 64-Bit) Would be very grateful for any advice :]

I'm currently using:

gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2

Edit:

Segmentation fault is usually a null pointer dereference. Given that libc is pretty solid, you most likely want to recompile your program with debug symbols, and get the debug variant of the Ubuntu package for libgvc.

The "Missing strlen_sse4.S" is just the debugger complaining that it can't find the file to give you a listing of the crash site. You need only get a copy of glibc source to examine the file.
