Sun knows about this problem.  It's Bug ID 4927647 in their database,
"pty loses last output before close/exit".  My test script follows:

for { set i 1 } { 1 } { incr i } {
    spawn echo foobarbaz
    expect {
	"foobarbaz" {
	    puts "ok"
	    expect eof
	    wait
	}
	eof {
	    puts "$i passes"
	    wait
	    exit 1
	}
    }
}
