Thank you for reporting this. I will test in a few hours and let you know if I can reproduce the issue.

[martinellimarco]

I can reproduce the bug, I'll investigate and resolve it as soon as possible.

[martinellimarco]

The problem is fixed. There was an unnecessary attempt to free a pointer at the end of the program. All archives produced with previous version are ok. A new release will be published soon. Thanks @amerlyq for reporting this.
