The GNU C Library (glibc) uses SSE instructions to make strlen (among
others) faster, loading 4 bytes at a time and reading past the end of
the allocated memory. This read is safe and when the strlen function
is inlined, it is (obviously) not replaced by valgrind, which reports
a false-possitive.
Tell valgrind to ignore this particular error, as the read is, in
fact, safe.
