Merged.

Resolved (in my repository - branch issue177)
This affected all search engines that allow heuristic lists.

This is in my repository, branch issue175.
But you can try any other parameter (reopen_closed) and I think the bug still 
happens

Erez, which repository or revision are you talking about? I do not have a bound
option in lazy_greedy...

Sure.

Sure. Gabi, can you look into this?

Sure, this workaround works [or just don't specify preferred=() ].
It's not urgent, but we should fix this.

As a workaround, have you tried specifying the arguments in a different order?

... "lazy_greedy(hff,hlm,bound=169009,preferred=())" ...

If this works, there's still a bug of course, but at least there'd be a workaround.

When I run this: 
./downward --heuristic 
"hlm,hff=lm_ff_syn(lm_rhw(reasonable_orders=true,cost_type=1,lm_cost_type=1))" -
-
search "lazy_greedy(hff,hlm,preferred=(),bound=169009)" < output

The bound is not passed to the search. When I removed the preferred=(), it 
works.
