It works in q.alt because q.alt is interpreted using the standard 
(lucene) query parser.

The dismax parser doesn't understand lucene syntax like *:* ... but *:* 
is typically the most common setting for q.alt, so Solr can't use dismax 
to interpret the q.alt query.

The edismax parser does understand *:* -- and it should be a superset of 
dismax functionality.  You MIGHT be able to use edismax instead of 
dismax without any changes.

Thanks,
Shawn
