This bug was reported a couple of weeks ago and is fixed in the next
beta. It should have given a 'noun result was required' message.

Now typing f 0 crashes.
The suspect

|infinite recursion
Doesn't seem to be the problem.

Solving Advent of Code, day 13, I think I ran into a bug in j904 beta-i
(likely doing something I shouldn't, but J shouldn't crash either: loading
the following slimmed-down file:
{{
line=: {{
+:y
}}
comp =: ([: *./ $:&>)`()`()@.cond
5
}}''
crashes J. When only the comp line is commented out, it does not crash, but
when both comp and 5 are commented, it crashes again. Since it also crashes
when comp is commented out, the nonsense in that line is not the (only)
problem...
