Thank you for your report.
Developers can't reproduce this issue in their test environment, therefore it would be good if you provide us login credential to your server for the further investigation. You can send it to me in PM.

 

[IgorG]

Custom version of dmarc is uploaded to the server. No more segfaults. Bugreport PPPM-7027 was created.
