Please send a test case, I can't replicate this. For example, the
following works fine:
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.
