If so, then that's a (minor) bug in Ikarus and Mosh.

Untrue. R6RS library section 7.1 says the syntax for
guard is
(guard (<variable>
<cond clause> <cond clause> ...)
<body>)
R6RS section 11.3 says the syntax for <body> is
<definition> ... <expression> <expression> ...
So definitions are definitely allowed in the body
of a guard.
