aoqi@0	25	* NASHORN-703
aoqi@0	26	*
aoqi@0	27	* Self modifying assignments and ++/-- operators had two issues
aoqi@0	28	* 1) the base was loaded twice
aoqi@0	29	* 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would
aoqi@0	30	* only be evaluated once, leading to bytecode stack underflow
aoqi@0	31	*
aoqi@0	32	* This file is split into two tests as the presence of eval affects the whole script
aoqi@0	33	*
aoqi@0	34	* @test
aoqi@0	35	* @run
