Reduces to this code:
use Devel::Peek;
for my $index (8066 .. 8150) {
my $c = chr($index);
Dump(uc $c);
print "$index\n";
}
which after a while gets you:
SV = PVMG(0x8be9928) at 0x8bb36a8
REFCNT = 1
FLAGS = (PADTMP,SMG,POK,pPOK,UTF8)
IV = 0
NV = 0
PV = 0xccd2008 "\341\275\255\316\231"\0 [UTF8 "\x{1f6d}\x{399}"]
CUR = 5
LEN = 67112948
MAGIC = 0x8c41108
MG_VIRTUAL = &PL_vtbl_utf8
MG_TYPE = PERL_MAGIC_utf8(w)
MG_LEN = 2
looks like the SvLEN of the PADTMP associated with the uc op is doubling
each second time round the loop.
Over to you, Jarkko ???
