jlaskey@3	25	* NASHORN-703
jlaskey@3	26	*
jlaskey@3	27	* Self modifying assignments and ++/-- operators had two issues
jlaskey@3	28	* 1) the base was loaded twice
jlaskey@3	29	* 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would
jlaskey@3	30	* only be evaluated once, leading to bytecode stack underflow
jlaskey@3	31	*
jlaskey@3	32	* This file is split into two tests as the presence of eval affects the whole script
jlaskey@3	33	*
jlaskey@3	34	* @test
jlaskey@3	35	* @run
