Original Redmine Comment Well the post butchered my code example. Let me know if you want me to provide an actual .pl Jeff |

Original Redmine Comment Are you using the most recent release? I thought all leaks were fixed in 2.230 - you'll see the t/48_leak.t test has almost the exact same loop you describe. So, maybe it's data dependent. |

Thanks for pointing me at that. So the difference between your test and mine is: If you have this then there isn't any memory growth. Without it the memory continues to grow. Jeff |

Original Redmine Comment Resolved... delete is needed. Based on your problems I looked at using weak references to solve this problem, but it can cause |

I don't know if this is a Verilog-Perl problem or a problem with perl.
If you do the following:
foreach my $vfile () {
my $nl = new Verilog::Netlist(....)
$nl->read_file(filename=>$vfile);
undef($nl);
}
You will see the memory grow with time, even if all the verilog files are the same size. It seems to me that the memory usage should be the that to cover the largest $nl ever used.
