OK, I guess you could have a workaround. The problem occurs only when
there are no non-sparse entries, which you can detect by (0 = 7&$.) In
that case (x i. y) will be 0 where y matches the sparse element,
otherwise (#x). That would be something like
fixedsvid =. i.`(((#@[)`0:)@.(=3&$.)~)@.(0=7 $. [)
Untested.

Thanks for fixing it.
(The no workaround bit is disappointing, given how many J versions
this hits. But maybe I can do something for the pritchard sieve...)
Thanks again,
