#8737 closed patch (fixed)

Fix crash bug in channel scanner

Reported by: Rune Petersen <rune@…> Owned by: Stuart Auchterlonie

Component: MythTV - Channel Scanner Version: 0.23-fixes

Description

ChannelScanSM doesn't delete the ScanStreamData? object in its, this results in a leak and a crash if ScanStreamData? calls one of the listeners after ChannelScanSM object has been deleted.

I would expect the crash to happen that often, because only new tables trigger calls to listeners. I am able to reliably reproduce this, because my DVB provider are constantly cycling NITo tables.

This patch also applies to trunk

I found another crash bug in ChannelScannerSM, a missing mutex... I'll see about updating the patch.
