  Modified files:
    lib/libc/string      strnstr.c 
  Log:
  strnstr() was testing one byte beyond the specified length in certain
  cases, which can cause a segfault if the 'big' string is not nul terminated
  and abutts unmapped memory space.
  
  This sort of thing can occur when a file is memory mapped and searched
  using strnstr().
