corrupted double-linked - Error in /usr/local/bin/bmdcapture #84

Closed advera68 closed 6 years ago

advera68 commented 7 years ago

Dear Luca,

This message was shown in Console (I enclose a copy of Backtrace and Memory Map bellow).

The server ( Operating System: Ubuntu 16.04 LTS ) has been working pretty well with a BlackMagic Decklink Duo, I use bmdcapture inside a loop (with a 1s delay) being interrupted according to other events.

As I told you the whole system works fine for weeks, I only have a look from time to time, for this reason I'm surprised to find this Error Message, by the way, the system has been rebooted.

What does "corrupted double-linked" mean ?

Thank you very much.

Regards.
