I believe this should work.  The manual says

 The last thing in the compound statement should be an expression
 followed by a semicolon; the value of this subexpression serves as the
 value of the entire construct.

Of course, there is a missing semicolon in the above; it should read

int result = ({
     struct test mytest;
     ({
         int testi;
         testi = func (&mytest);
         testi;
     });
});

but that should work.  In fact, it does for me.
