SEGFAULT with Full Scan (Tuned) using DVB-S

Reported by: Nick Morrott <knowledgejunkie (at) gmail (dot) com> Owned by: Janne Grunau
Priority: minor Milestone: 0.22
Component: MythTV - Channel Scanner Version: head
Severity: medium Keywords:
Cc: Ticket locked: no


Have been seeing segfaults with the most recent version of the channel scanner. I'm usually starting the full scan by tuning to 10773000kHz, with and without encryption testing enabled.

Attached are the gdb traces of what seems to be 4 segfaults. I have been having problems triggering the segfault consistently, and in my experience the segfault was most observed when running a release build (so most unhelpful for debugging). Debug builds seemed better in my limited testing, profile builds seemed prone to hang during scanning.

The issue seems to lie in ChannelScanSM::UpdateChannelInfo?(bool).

Apologies if these backtraces are not helpful (I am new to gdb). I will continue to try to get a debug build to segfault a few more times to be helpful.

hopefully fixes #6915
