[Ecls-list] uninitialized ihs_frame object in call to ecl_cs_check

Hi Juanjo,

  I was investigating some obscure `segmentation fault' (on MAC OS) or
`stack over flow' (on x86) bug in a ECL-based OpenAxiom build, when I
got prompted to look into src/c/interpreter.d:ecl_interpret().  It looks
to me that given:

        struct ecl_stack_frame frame_aux;
        volatile struct ihs_frame ihs;


the object `ihs' is never initialized before call to ecl_cs_check.
That looks to me like a serious bug.
