Hello Monks,

I'm wondering about the following code snippet that triggers a segmentation fault if the script exit.

my $i = 30000;
my %h = (new => {});
my $r = \%h;
for (0..$i) {
   print $_, " ";
   $r = $r->{new};
   $r->{new} = {};
}
print "end\n";
[download]

Output:

...29998 29999 30000 end
Segmentation fault (core dumped)
[download]

I test it with different iterations and from 24.000 the segfault is produced definitely. If I try to undef %h the segfault is produced immediate.

my $i = 30000;
my %h = (new => {});
my $r = \%h;
for (0..$i) {
   print $_, " ";
   $r = $r->{new};
   $r->{new} = {};
}
undef %h;
print "end\n";
[download]

Output: 29837 29838 29839 29840 Segmentation fault (core dumped)
My question is now why that happend? Do you have an answer?

Regards,
Jonny

Edit: g0n - changed pre tags to code tags
