It is almost totally unclear for the list readers including myself what you
are seeing. You haven't included the actual error message or detailed output,
and with "working example" I mean a script that I can run on my gretl
installation, preferably using a built-in example dataset.

How can "[...](1-b3)" work in gretl's language hansl? AFAICS it has to be
"(...)*(1-b3)" at least. If gretl doesn't return an error at this point,
that's already strange and might be a parsing bug.
There was a bug here (now fixed in git), in the sense that when the
right-hand side of a restriction was garbage (as above) this was being
replaced by zero without an error being flagged.
We were being too trusting -- assuming that users would have read the
doc on "restrict" and would therefore just supply a scalar value on
the right, as stipulated. Now we check rigorously.
