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 |
