LiveTV Segfaults when a channel is selected

Reported by: nathan smith <tsx_5@…> Owned by: stuartm
Priority: critical Milestone: 0.24
Component: MythTV - General Version: head
Severity: high Keywords:
Cc: Ticket locked: no

Description

This segfault is repeatable (for me) by starting livetv, which brings up the guide, and then selecting a channel -- which causes it to immediately fail. Up till that point, sound and video seem are working. I am using SVN updated today. GDB.txt will be attached.

The gdb.txt is *edited* -- I cut out about 65M of data.... However, It's just a whole lot of a single line being repeated.

Only the first number increments.

Resolution: fixed
Status: acceptedclosed

(In [23821]) Quick fix to the loop created by [23802] when changing channels in livetv via the guide grid. The cast that the original commit removed seems like a hack, or at least a trick I'm not aware of which allowed a const function to call a non-const function, if we can confirm that it's legimate then it may be re-instated but for now I've just duplicated the non-const GetChannelInfo?() for the sake of expendiency. Fixes #8231
