A good segfault recipe if y is shorter than x. Beside that, strlen() + memcmp() may be somewhat faster or somewhat slower than strcmp() when the strings are equal (depdens on implementation), but it's is order of magnitude(!) slower when the strings differ near their begining. The lesson is to use strcmp() for string comparison.
