Although I don't know your hardware setup it looks like gets() is
returning EOF on the second call to it, gets() should return a
nil-string.  The subtle difference is that gets() should return a
nil-string (i.e. "") if you only type a newline and it should return
a NULL pointer to signal EOF or a read error.  Try the same program
on any UNIX box and type ^D (EOF) on the second gets().  Hope this
helps,
