I see you removed the "rvalue" reference...

Anyway, the code of D::S does this: 

   if (AvMAX(thing) != -1) {
      /* an array with 10 slots has AvMax() set to 9 - te 2007-04-22 *
+/
      total_size += sizeof(SV *) * (AvMAX(thing) + 1);

And AvMAX is defined as: 

#define AvMAX(av)    ((XPVAV*)  SvANY(av))->xav_max

[download]

Ie. It simply gets the value from a struct member.

It also references AvALLOC & AvARYLEN, but neither of those does anything with magic either: 

#define AvARRAY(av)    ((av)->sv_u.svu_array)
#define AvALLOC(av)    (*((SV***)&((XPVAV*)  SvANY(av))->xav_alloc))
#define AvMAX(av)    ((XPVAV*)  SvANY(av))->xav_max
#define AvFILLp(av)    ((XPVAV*)  SvANY(av))->xav_fill
#define AvARYLEN(av)    (*Perl_av_arylen_p(aTHX_ MUTABLE_AV(av)))

[download]

The only "method" that touches magic is AvFILL: 

#define AvFILL(av)    ((SvRMAGICAL((const SV *) (av))) \
             ? mg_size(MUTABLE_SV(av)) : AvFILLp(av))

[download]

And AvFILL doesn't appear anywhere in the D::S source.

So, I say again, the bug does not lie with D::S.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
