25 * NASHORN-703
26 *
27 * Self modifying assignments and ++/-- operators had two issues
28 * 1) the base was loaded twice
29 * 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would
30 *    only be evaluated once, leading to bytecode stack underflow
31 *
32 * This file is split into two tests as the presence of eval affects the whole script
33 *
34 * @test
35 * @run
