This is kind of just idle wondering, but does anyone have an idea of where 'REFCNT = 2147480012' arises from when dumping undef as a constant.

use Devel::Peek; my $scalar; Dump($scalar); Dump(undef); Dump(5); Dump('abc'); # SV = NULL(0x0) at 0x250b98c # REFCNT = 1 # FLAGS = (PADMY) # SV = NULL(0x0) at 0x9f3788 # REFCNT = 2147480012 # FLAGS = (READONLY) # SV = IV(0x250b998) at 0x250b99c # REFCNT = 1 # FLAGS = (PADTMP,IOK,READONLY,pIOK) # IV = 5 # SV = PV(0x261b534) at 0x25021b4 # REFCNT = 1 # FLAGS = (PADTMP,POK,READONLY,pPOK) # PV = 0x2716f54 "abc"\0 # CUR = 3 # LEN = 4
