Comment 13 for bug 852760

The
#include <stdlib.h>
#include <string.h>

__attribute__((noinline)) void
foo (void *p)
{
  memcpy (p, "0123456789abcd", 15);
}

int
main (void)
{
  void *p = malloc (15);
  foo (p);
  return strlen (p) - 14;
}
testcase where strlen does this is expanded that way with GCC 4.6 (currently used e.g. in Fedora 15) with default options, but e.g. 4.5 or even earlier versions expand this the same way with -O2 -minline-all-stringops.
