#7345 closed defect (invalid)

Memory corruption in mythbackend after failed recording of HD-PVR

Reported by: kenneth.emerson@… Owned by: danielk
Priority: minor Milestone: unknown
Component: MythTV - Recording Version: head
Severity: medium Keywords:
Cc: Ticket locked: no


Either the HD-PVR is not configured properly in myth or the v4l driver has a problem coexisting between the HD-PVR and the HVR-1800 in the same computer (guess). After completing a failed recording attempt on /dev/video0, the backend faults with a malloc error (memory corruption).

For any memory corruption please attach a valgrind log.

I'm closing this ticket only because of it's age. If you can reproduce with 0.23, please open a new ticket with the valgrind log in addition to the backend log.

FWIW, I just experienced this crash in 0.23 (25145) a few minutes ago (and apparently last night as well). I've restarted the backend under valgrind. I'll let you know if/when I get another crash.
