Sorry for the late reply... could you file a bug on sourceforge so we
can keep track of this problem, and also include a simple example .i
file that exhibits the problem?  I will take a look at it.

Thanks,
John

Actually, I just tried in a .i file (on the latest SVN... Revision 9846)


%inline %{
/* Chicken had a problem when wrapping a class name with an underscore
in a helper function */
class Test_Underscore {
  public:
    int a;
};

int test_underscore(Test_Underscore *t) {
  return t->a;
}
%}

and in cpp_basic.scm I got

(define-method (test-underscore  (arg0 <Test-Underscore>)) ((vector-ref
swig-init-return 27)  (slot-ref arg0 'swig-this)))

so perhaps you could try the latest verion 1.3.31 or latest SVN (not
much has changed between 1.3.31 and the latest SVN for the chicken module).
