It looks like one of the flags added for mjsunit tests is breaking this:
It breaks with the following configuration:
out/x64.release/d8 --random-seed=454874028 --turbo-filter=* --always-opt
--nohard-abort --nodead-code-elimination --nofold-constants
--harmony-arrays
--harmony-generators
V8 version 3.29.13 (candidate) [console: dumb]
d8> (function() { function* generator() { yield '1'; yield '2';
yield '3'; }
return Array.from(generator()); })()

But if you just pass --harmony-arrays --harmony-generators, it works as
expected
Probably related to TurboFan. I see other generator tests being disabled:
