Hi Christian,
thanks, fixed in SVN 617. The problem was caused by a -∞ result
from ⍟.
There could still be some functions around that return ∞. Such functions should
raise a DOMAIN ERROR instead. Please report such functions
if you see them.
Got some kind of limit bug. When my function '∆' is called with an undefined
function name
it core dump. I understood why and fixed the function by addind the line #2
(actually commented out).
Nevertheless, I report this because it abort rather than give some APL errors.
Session:
$ aplt
