Great trouble report. I can reproduce it. The problem is that a
read-only value (like i. 7) erroneously becomes inplaceable when
returned from an explicit definition.
Workaround: make the value not read-only, as with
itoms=: 3 : '00 + i.7'

Don't worry too much about getting a small failure - any reproducible
failure will do.

I don't think the mischief is being done by pack_cal_ but by its
calling
verb: arrowch_cal_ .
The latter somehow munges a presumed cache of (i.) values, and
pack_cal_
falls over as a result.
I'm busy teasing out a simple standalone code sample. But I thought I'd
report the bug right away since it is insidious and impactful.
Same thing happens in j902 too, but not in j901.
