I thought I put in enough asserts to stop this from SEGVing or nobody CPANTesters with DEBUGGING on?

/* these CvPADLIST/CvRESERVED asserts can be reverted one day, once stabilized */
#define CvPADLIST(sv) (*(assert_(!CvISXSUB((CV*)(sv))) \
  &(((XPVCV*)MUTABLE_PTR(SvANY(sv)))->xcv_padlist_u.xcv_padlist)))
/* CvPADLIST_set is not public API, it can be removed one day, once stabilized */
#ifdef DEBUGGING
# define CvPADLIST_set(sv, padlist) Perl_set_padlist((CV*)sv, padlist)
#else
# define CvPADLIST_set(sv, padlist) (CvPADLIST(sv) = (padlist))
#endif
