check_antennas double free segfault #3329

Closed gadfort closed 1 year ago

gadfort commented 1 year ago

Describe the bug

When running check_antennas it results in a double free or corruption segfault. In this case, the net was rst_ni

Here is the backtrace:

Hi @gadfort, I've been looking into your bug for the last week but it seems to be fixed in the latest versions of OR (commit grt: do not create virtual wires on first routing layer). Could you run the test again with the most recent version of OR and confirm that the bug is gone? I will be waiting for your confirmation

@luis201420 I don't see the issue anymore. Thanks for checking. I'll close the issue.
