Ok, it seems to be related to calling a user-defined function after 
estimation and before the restriction test; here is a demo script:

<script>
open denmark

function trivial(void)
result = 1
return scalar result
end function

ols LRM 0 LRY
scalar check = trivial()
omit LRY
</script>

This gives the mentioned error on today's CVS. I can't guarantee right 
now that this demo script works with 1.7.4, but our real-world script 
(where we noticed the bug) did.

In this case there is obviously an easy workaround (move the function 
call after the omit), but I can imagine cases where you want to use 
'restrict' with some value that you need to calculate in a function 
beforehand. So I'm inclined to think it's a bug.
