( #3333=superdoc: print w/replies, xml ) Need Help??

Thanks for the reply demerphq. But I think you've confused me more.

I thought my mortalized SVs were only supposed to be blown away when the following code gets executed:


So how could the values be freed too soon?

Also, if what you say is true, then I'd think it would hold true for storing values in a hash, too. But I experimented, and it seems like there, I have to mortalize the SVs I am storing in the hash, or there's a leak:

HV *hash = (HV *)sv_2mortal((SV *) newHV()); SV *type = newSVpv("string", 0); //SV *type = sv_2mortal(newSVpv("string", 0)); SvREFCNT_inc( type ); if ( NULL == hv_store( hash, "type", strlen("type"), type, 0) ) { SvREFCNT_dec( type ); printf("hv_store failed\n"); exit(1); } XPUSHs(sv_2mortal(newRV((SV *)hash)));

That leaks, but if I mortalize the SV as in the comment, everything is great, and there are no warnings. So what gives? What's the difference between the av_push and hv_store examples?
