When we add Join(finiteAggregate) it works; strange isn't it. Why?
)abbrev domain FOO Foo
Foo(): Exports == Implementation where
Exports == Join(finiteAggregate) with
foo: () -> Boolean
Implementation == add
foo(): Boolean ==
a: List List Integer := empty()
b: List List
After some thinking I don't find it so strange anymore that adding
'finiteAgggregate' is a remedy. The domain FOOX (only one List) works without
this because S=Integer, whereas in FOO we have S=List Integer where some info
may be get lost in the recursion.

You're right, of course. The root of all evil (not all, though) in TEX is found
in OUTFORM.

Thanks for the hint. Actually this was discussed several times in the forum:
https://groups.google.com/forum/#!searchin/fricas-devel/dynamic-space-size%7Csort:date
Nevertheless this might be always an option, as a last resort ;)
If it could be fixed in the code, however, then it should be done.
Good :)
BTW I compiled yesterday the current rev (fresh clone). I guess the version
dates (2018) were already wrong in the last release (1.3.5 / 3 February 2019;

there a special policy?

Although I'm not a lisp expert nor exactly understand the goal, I suggest
combining "mathprint" with the FORMAT function (~%: newline):
(1) -> print(x) == (mathprint(x)$Lisp; FORMAT('T,"~% ~% ~%")$Lisp)
(2) -> print3(x^n+2::OutputForm)
Compiling function print3 with type OutputForm -> SExpres

The strange thing is, that *now* there's no need to get the macros out of the
body ;) Hence, I guess the problem is related to type coercion. If you could
rewrite the macros to local functions (w. types), e.g. minrootpol(X:Type):?,
