octave-antonio: libinterp/parse-tree/pt-eval.cc annotate

annotate libinterp/parse-tree/pt-eval.cc @ 19218:0279c601b49c stable

compute for loop indices consistently with range element results * pt-eval.cc (tree_evaluator::visit_simple_for_command): Use Range::elem instead of compuiting elements directly. This change appears to fix obscure test failures in eig.cc-tst on 64-bit Windows systems. See also task #13313.
