So your test case is

(intern-soft 'does-not-exist)

?

That's not a valid use case for the function -- the reader will intern
`does-not-exist', and so the `intern-soft' call will just return the
interned symbol.  The function is meant to be used like:

(intern-soft "does-not-exist")

So I'm closing this bug reprt.
