ruby and I'm guessing other apps pass a null buffer to getcwd, expecting to use the return value rather than having data written into the destination buffer. this obviously causes an illegal access. this patch fixes it by having fakedir's getcwd check if the destination buffer is valid and allocating a new buffer with strdup if it isn't.
