Bug Description
Binary package hint: busybox-static
$ echo "a" | busybox sed -e 's,a,b,'
Illegal instruction (core dumped)
$ busybox --help | grep ^Busy
BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu1) multi-call binary
$ dpkg -S `which busybox`
busybox-static: /bin/busybox
$ dpkg-query --show busybox-static
busybox-static 1:1.15.3-1ubuntu1
I believe this is a problem due to running in xen on ec2. Below is the backtrace from gdb.

It is moderately annoying, because there is noclean way to really replace busybox-static with busybox , because ubuntu-standard depends on busybox. 'busybox' does not have this problem.

Description of problem:
compiling a minimal test application statically using gcc, the call strspn() causes a SIGILL. Prints "Illegal instruction" on the command line.
Changing "char var[]" to "char *var" for strtext and cset causes the problem to decrease from always occuring despite optimization level to occuring only during -O0.
Does not occur for dynamically linked application.
Version-Release number of selected component (if applicable):
glibc-static-2.12-3
How reproducible:
Every time.
Steps to Reproduce:
1. Compile main.c below (strspn test) with "gcc main.c -g -static -O0 -o testapp.bin"
2. Run ./testapp.bin
3. Run gdb ./testapp.bin
Actual results:
When ran from the command line, output is "Illegal instruction"
When ran from the debugger, output is
Program received signal SIGILL, Illegal instruction.
0x08052f5d in __strspn_sse42 ()
Expected results:
Prints-"The length of initial number is 3."

int i;
i = strspn( strtext, cset );
printf ( "The length of initial number is %d.\n", i );
return 0;
