[STRUCT] random mechanism in struct does not work

[yyb0205]

Test Program:

component pss_top {

    struct my_struct {
        int a = 1;
        rand int b;
        rand int c;
        constraint {
            b == 2;
        }
    }

    action root_a {
        my_struct s1;
        int x, y, z;

        constraint {
            s1.c == 3;
        }

        exec post_solve {
            x = s1.a;
            y = s1.b;
            z = s1.c;
        }
        exec body ASM = """x = {{x}}
y = {{y}}
z = {{z}}""";
    }
}

Error Message:

PSSRandom.limitRetry(), Ln47: randomize fail

Golden Result:

x = 1
y = 2
z = 3
