You can not just cast a char* to a SCM.  Where did you get that idea?
(Maybe there is some misleading stuff in the manual, that's why I
ask.)

You should either use scm_c_eval_string,

    scm_c_eval_string ("(test_function 4)");

wich can work directly with C strings, or use scm_str2string to
convert the C string into a Scheme string:

    scm_c_eval_string (scm_str2string ("(test_function 4)"));
